The (1) aac_cfg_open and (2) aac_compat_ioctl functions in the SCSI layer ioctl path in aacraid in the Linux kernel before 2.6.23-rc2 do not check permissions for ioctls, which might allow local users to cause a denial of service or gain privileges.

From Red Hat Security Advisory 2007:1049 :

Updated kernel packages that fix several security issues and a bug in the Red Hat Enterprise Linux 3 kernel are now available.

This update has been rated as having important security impact by the Red Hat Security Response Team.

The kernel packages contain the Linux kernel, the core of any Linux operating system.

A flaw was found in the handling of process death signals. This allowed a local user to send arbitrary signals to the suid-process executed by that user. A successful exploitation of this flaw depends on the structure of the suid-program and its signal handling.
(CVE-2007-3848, Important)

A flaw was found in the IPv4 forwarding base. This allowed a local user to cause a denial of service. (CVE-2007-2172, Important)

A flaw was found where a corrupted executable file could cause cross-region memory mappings on Itanium systems. This allowed a local user to cause a denial of service. (CVE-2006-4538, Moderate)

A flaw was found in the stack expansion when using the hugetlb kernel on PowerPC systems. This allowed a local user to cause a denial of service. (CVE-2007-3739, Moderate)

A flaw was found in the aacraid SCSI driver. This allowed a local user to make ioctl calls to the driver that should be restricted to privileged users. (CVE-2007-4308, Moderate)

As well, these updated packages fix the following bug :

* a bug in the TCP header prediction code may have caused 'TCP:
Treason uncloaked!' messages to be logged. In certain situations this may have lead to TCP connections hanging or aborting.

Red Hat Enterprise Linux 3 users are advised to upgrade to these updated packages, which contain backported patches to resolve these issues.

From Red Hat Security Advisory 2007:0939 :

Updated kernel packages that fix various security issues in the Red Hat Enterprise Linux 4 kernel are now available.

This update has been rated as having important security impact by the Red Hat Security Response Team.

The Linux kernel is the core of the operating system.

These updated kernel packages contain fixes for the following security issues :

* A flaw was found in the handling of process death signals. This allowed a local user to send arbitrary signals to the suid-process executed by that user. A successful exploitation of this flaw depends on the structure of the suid-program and its signal handling.
(CVE-2007-3848, Important)

* A flaw was found in the CIFS file system. This could cause the umask values of a process to not be honored on CIFS file systems where UNIX extensions are supported. (CVE-2007-3740, Important)

* A flaw was found in the VFAT compat ioctl handling on 64-bit systems. This allowed a local user to corrupt a kernel_dirent struct and cause a denial of service. (CVE-2007-2878, Important)

* A flaw was found in the Advanced Linux Sound Architecture (ALSA). A local user who had the ability to read the /proc/driver/snd-page-alloc file could see portions of kernel memory. (CVE-2007-4571, Moderate)

* A flaw was found in the aacraid SCSI driver. This allowed a local user to make ioctl calls to the driver that should be restricted to privileged users. (CVE-2007-4308, Moderate)

* A flaw was found in the stack expansion when using the hugetlb kernel on PowerPC systems. This allowed a local user to cause a denial of service. (CVE-2007-3739, Moderate)

* A flaw was found in the handling of zombie processes. A local user could create processes that would not be properly reaped which could lead to a denial of service. (CVE-2006-6921, Moderate)

* A flaw was found in the CIFS file system handling. The mount option 'sec=' did not enable integrity checking or produce an error message if used. (CVE-2007-3843, Low)

* A flaw was found in the random number generator implementation that allowed a local user to cause a denial of service or possibly gain privileges. This flaw could be exploited if the root user raised the default wakeup threshold over the size of the output pool.
(CVE-2007-3105, Low)

Additionally, the following bugs were fixed :

* A flaw was found in the kernel netpoll code, creating a potential deadlock condition. If the xmit_lock for a given network interface is held, and a subsequent netpoll event is generated from within the lock owning context (a console message for example), deadlock on that cpu will result, because the netpoll code will attempt to re-acquire the xmit_lock. The fix is to, in the netpoll code, only attempt to take the lock, and fail if it is already acquired (rather than block on it), and queue the message to be sent for later delivery. Any user of netpoll code in the kernel (netdump or netconsole services), is exposed to this problem, and should resolve the issue by upgrading to this kernel release immediately.

* A flaw was found where, under 64-bit mode (x86_64), AMD processors were not able to address greater than a 40-bit physical address space;
and Intel processors were only able to address up to a 36-bit physical address space. The fix is to increase the physical addressing for an AMD processor to 48 bits, and an Intel processor to 38 bits. Please see the Red Hat Knowledgebase for more detailed information.

* A flaw was found in the xenU kernel that may prevent a paravirtualized guest with more than one CPU from starting when running under an Enterprise Linux 5.1 hypervisor. The fix is to allow your Enterprise Linux 4 Xen SMP guests to boot under a 5.1 hypervisor.
Please see the Red Hat Knowledgebase for more detailed information.

These new kernel packages contain fixes for the following security issues :

  - A flaw was found in the backported stack unwinder fixes     in Red Hat Enterprise Linux 5. On AMD64 and Intel 64     platforms, a local user could trigger this flaw and     cause a denial of service. (CVE-2007-4574, Important)

  - A flaw was found in the handling of process death     signals. This allowed a local user to send arbitrary     signals to the suid-process executed by that user. A     successful exploitation of this flaw depends on the     structure of the suid-program and its signal handling.
    (CVE-2007-3848, Important)

  - A flaw was found in the Distributed Lock Manager (DLM)     in the cluster manager. This allowed a remote user who     is able to connect to the DLM port to cause a denial of     service. (CVE-2007-3380, Important)

  - A flaw was found in the aacraid SCSI driver. This     allowed a local user to make ioctl calls to the driver     which should otherwise be restricted to privileged     users. (CVE-2007-4308, Moderate)

  - A flaw was found in the prio_tree handling of the     hugetlb support that allowed a local user to cause a     denial of service. This only affected kernels with     hugetlb support. (CVE-2007-4133, Moderate)

  - A flaw was found in the eHCA driver on PowerPC     architectures that allowed a local user to access 60k of     physical address space. This address space could contain     sensitive information. (CVE-2007-3850, Moderate)

  - A flaw was found in ptrace support that allowed a local     user to cause a denial of service via a NULL pointer     dereference. (CVE-2007-3731, Moderate)

  - A flaw was found in the usblcd driver that allowed a     local user to cause a denial of service by writing data     to the device node. To exploit this issue, write access     to the device node was needed. (CVE-2007-3513, Moderate)

  - A flaw was found in the random number generator     implementation that allowed a local user to cause a     denial of service or possibly gain privileges. If the     root user raised the default wakeup threshold over the     size of the output pool, this flaw could be exploited.
    (CVE-2007-3105, Low)

In addition to the security issues described above, several bug fixes preventing possible system crashes and data corruption were also included.

This kernel update fixes the following security problems :

  - The sysfs_readdir function in the Linux kernel 2.6     allows local users to cause a denial of service (kernel     OOPS) by dereferencing a NULL pointer to an inode in a     dentry. (CVE-2007-3104)

  - A 2 byte buffer underflow in the ieee80211 stack was     fixed, which might be used by attackers in the local     WLAN reach to crash the machine. (CVE-2007-4997)

  - The CIFS filesystem, when Unix extension support is     enabled, did not honor the umask of a process, which     allowed local users to gain privileges. (CVE-2007-3740)

  - It was possible for local user to become root by     exploiting a bug in the IA32 system call emulation. This     problem affects the x86_64 platform only, on all     distributions. (CVE-2007-4573)

    This problem was fixed for regular kernels, but had not     been fixed for the XEN kernels. This update fixes the     problem also for the XEN kernels.

  - The (1) aac_cfg_open and (2) aac_compat_ioctl functions     in the SCSI layer ioctl path in aacraid did not check     permissions for ioctls, which might have allowed local     users to cause a denial of service or gain privileges.
    (CVE-2007-4308)

  - The Linux kernel checked the wrong global variable for     the CIFS sec mount option, which might allow remote     attackers to spoof CIFS network traffic that the client     configured for security signatures, as demonstrated by     lack of signing despite sec=ntlmv2i in a SetupAndX     request. (CVE-2007-3843)

  - Multiple buffer overflows in CIFS VFS in the Linux     kernel allowed remote attackers to cause a denial of     service (crash) and possibly execute arbitrary code via     long SMB responses that trigger the overflows in the     SendReceive function. (CVE-2007-5904)

    This requires the attacker to mis-present / replace a     CIFS server the client machine is connected to.

  - Buffer overflow in the isdn_net_setcfg function in     isdn_net.c in the Linux kernel allowed local users to     have an unknown impact via a crafted argument to the     isdn_ioctl function. (CVE-2007-6063)

* A flaw was found in ptrace support that allowed a local user to cause a denial of service via a NULL pointer dereference.
(CVE-2007-3731, Moderate)

* A flaw was found in the usblcd driver that allowed a local user to cause a denial of service by writing data to the device node. To exploit this issue, write access to the device node was needed.
(CVE-2007-3513, Moderate)

* A flaw was found in the random number generator implementation that allowed a local user to cause a denial of service or possibly gain privileges. If the root user raised the default wakeup threshold over the size of the output pool, this flaw could be exploited.
(CVE-2007-3105, Low)

In addition to the security issues described above, several bug fixes preventing possible system crashes and data corruption were also included.

Red Hat Enterprise Linux 5 users are advised to upgrade to these packages, which contain backported patches to resolve these issues.

I  Updated ESX driver

    a. Updated aacraid driver

       This patch fixes a flaw in how the aacraid SCSI driver checked        IOCTL command permissions.  This flaw might allow a local user        on the Service Console to cause a denial of service or gain        privileges. Thanks to Adaptec for reporting this issue.

       The Common Vulnerabilities and Exposures project (cve.mitre.org)        has assigned the name CVE-2007-4308 to this issue.

II  Service Console package security updates

    a. Samba

       Alin Rad Pop of Secunia Research found a stack-based buffer overflow        flaw in the way Samba authenticates remote users.  A remote        unauthenticated user could trigger this flaw to cause the Samba        server to crash or to execute arbitrary code with the        permissions of the Samba server.

       Note: This vulnerability can be exploited only if the attacker              has access to the Service Console network.  The Samba              client is installed by default in the Service Console, but              the Samba server is not.

       The Common Vulnerabilities and Exposures project (cve.mitre.org)        has assigned the name CVE-2007-6015 to this issue.

    b. Python

       Chris Evans of the Google security research team discovered an        integer overflow issue with the way Python's Perl-Compatible        Regular Expression (PCRE) module handled certain regular        expressions.  If a Python application used the PCRE module to        compile and execute untrusted regular expressions, it might be        possible to cause the application to crash, or to execute        arbitrary code with the privileges of the Python interpreter.

       The Common Vulnerabilities and Exposures project (cve.mitre.org)        has assigned the name CVE-2006-7228 to this issue.

       Piotr Engelking discovered a flaw in Python's locale module        where strings generated by the strxfrm() function were not        properly NUL-terminated.  This might result in disclosure of        data stored in the memory of a Python application using the        strxfrm() function.

       The Common Vulnerabilities and Exposures project (cve.mitre.org)        has assigned the name CVE-2007-2052 to this issue.

       Slythers Bro reported multiple integer overflow flaws in        Python's imageop module.  These could allow an attacker to cause        a Python application to crash, enter an infinite loop, or        possibly execute arbitrary code with the privileges of the        Python interpreter.

       The Common Vulnerabilities and Exposures project (cve.mitre.org)        has assigned the name CVE-2007-4965 to this issue.

Updated kernel packages that fix various security issues in the Red Hat Enterprise Linux 4 kernel are now available.

This update has been rated as having important security impact by the Red Hat Security Response Team.

The Linux kernel is the core of the operating system.

These updated kernel packages contain fixes for the following security issues :

* A flaw was found in the handling of process death signals. This allowed a local user to send arbitrary signals to the suid-process executed by that user. A successful exploitation of this flaw depends on the structure of the suid-program and its signal handling.
(CVE-2007-3848, Important)

* A flaw was found in the CIFS file system. This could cause the umask values of a process to not be honored on CIFS file systems where UNIX extensions are supported. (CVE-2007-3740, Important)

* A flaw was found in the VFAT compat ioctl handling on 64-bit systems. This allowed a local user to corrupt a kernel_dirent struct and cause a denial of service. (CVE-2007-2878, Important)

* A flaw was found in the Advanced Linux Sound Architecture (ALSA). A local user who had the ability to read the /proc/driver/snd-page-alloc file could see portions of kernel memory. (CVE-2007-4571, Moderate)

* A flaw was found in the aacraid SCSI driver. This allowed a local user to make ioctl calls to the driver that should be restricted to privileged users. (CVE-2007-4308, Moderate)

* A flaw was found in the stack expansion when using the hugetlb kernel on PowerPC systems. This allowed a local user to cause a denial of service. (CVE-2007-3739, Moderate)

* A flaw was found in the handling of zombie processes. A local user could create processes that would not be properly reaped which could lead to a denial of service. (CVE-2006-6921, Moderate)

* A flaw was found in the CIFS file system handling. The mount option 'sec=' did not enable integrity checking or produce an error message if used. (CVE-2007-3843, Low)

* A flaw was found in the random number generator implementation that allowed a local user to cause a denial of service or possibly gain privileges. This flaw could be exploited if the root user raised the default wakeup threshold over the size of the output pool.
(CVE-2007-3105, Low)

Additionally, the following bugs were fixed :

* A flaw was found in the kernel netpoll code, creating a potential deadlock condition. If the xmit_lock for a given network interface is held, and a subsequent netpoll event is generated from within the lock owning context (a console message for example), deadlock on that cpu will result, because the netpoll code will attempt to re-acquire the xmit_lock. The fix is to, in the netpoll code, only attempt to take the lock, and fail if it is already acquired (rather than block on it), and queue the message to be sent for later delivery. Any user of netpoll code in the kernel (netdump or netconsole services), is exposed to this problem, and should resolve the issue by upgrading to this kernel release immediately.

* A flaw was found where, under 64-bit mode (x86_64), AMD processors were not able to address greater than a 40-bit physical address space;
and Intel processors were only able to address up to a 36-bit physical address space. The fix is to increase the physical addressing for an AMD processor to 48 bits, and an Intel processor to 38 bits. Please see the Red Hat Knowledgebase for more detailed information.

* A flaw was found in the xenU kernel that may prevent a paravirtualized guest with more than one CPU from starting when running under an Enterprise Linux 5.1 hypervisor. The fix is to allow your Enterprise Linux 4 Xen SMP guests to boot under a 5.1 hypervisor.
Please see the Red Hat Knowledgebase for more detailed information.

Red Hat Enterprise Linux 4 users are advised to upgrade to these updated packages, which contain backported patches to correct these issues.

Updated kernel packages that fix a number of security issues are now available for Red Hat Enterprise Linux 2.1 running on 32-bit architectures.

This update has been rated as having important security impact by the Red Hat Security Response Team.

The kernel packages contain the Linux kernel, the core of any Linux operating system.

These updated packages fix the following security issues :

* a flaw was found in the IPv4 forwarding base. This could allow a local, unprivileged user to cause a denial of service. (CVE-2007-2172, Important)

* a flaw was found in the handling of process death signals. This allowed a local, unprivileged user to send arbitrary signals to the suid-process executed by that user. Successful exploitation of this flaw depends on the structure of the suid-program and its signal handling. (CVE-2007-3848, Important)

* when accessing kernel memory locations, certain Linux kernel drivers registering a fault handler did not perform required range checks. A local, unprivileged user could use this flaw to gain read or write access to arbitrary kernel memory, or possibly cause a denial of service. (CVE-2008-0007, Important)

* a possible kernel memory leak was found in the Linux kernel Simple Internet Transition (SIT) INET6 implementation. This could allow a local, unprivileged user to cause a denial of service. (CVE-2008-2136, Important)

* missing capability checks were found in the SBNI WAN driver which could allow a local, unprivileged user to bypass intended capability restrictions. (CVE-2008-3525, Important)

* a flaw was found in the way files were written using truncate() or ftruncate(). This could allow a local, unprivileged user to acquire the privileges of a different group and obtain access to sensitive information. (CVE-2008-4210, Important)

* a race condition in the mincore system core allowed a local, unprivileged user to cause a denial of service. (CVE-2006-4814, Moderate)

* a flaw was found in the aacraid SCSI driver. This allowed a local, unprivileged user to make ioctl calls to the driver which should otherwise be restricted to privileged users. (CVE-2007-4308, Moderate)

* two buffer overflow flaws were found in the Integrated Services Digital Network (ISDN) subsystem. A local, unprivileged user could use these flaws to cause a denial of service. (CVE-2007-6063, CVE-2007-6151, Moderate)

* a flaw was found in the way core dump files were created. If a local, unprivileged user could make a root-owned process dump a core file into a user-writable directory, the user could gain read access to that core file, potentially compromising sensitive information.
(CVE-2007-6206, Moderate)

* a deficiency was found in the Linux kernel virtual file system (VFS) implementation. This could allow a local, unprivileged user to attempt file creation within deleted directories, possibly causing a denial of service. (CVE-2008-3275, Moderate)

All users of Red Hat Enterprise Linux 2.1 on 32-bit architectures should upgrade to these updated packages which address these vulnerabilities. For this update to take effect, the system must be rebooted.

Several local and remote vulnerabilities have been discovered in the Linux kernel that may lead to a denial of service or the execution of arbitrary code. The Common Vulnerabilities and Exposures project identifies the following problems :

  - CVE-2006-5823     LMH reported a potential local DoS which could be     exploited by a malicious user with the privileges to     mount and read a corrupted cramfs filesystem.

  - CVE-2006-6054     LMH reported a potential local DoS which could be     exploited by a malicious user with the privileges to     mount and read a corrupted ext2 filesystem.

  - CVE-2006-6058     LMH reported an issue in the minix filesystem that     allows local users with mount privileges to create a DoS     (printk flood) by mounting a specially crafted corrupt     filesystem.

  - CVE-2006-7203     OpenVZ Linux kernel team reported an issue in the smbfs     filesystem which can be exploited by local users to     cause a DoS (oops) during mount.

  - CVE-2007-1353     Ilja van Sprundel discovered that kernel memory could be     leaked via the Bluetooth setsockopt call due to an     uninitialized stack buffer. This could be used by local     attackers to read the contents of sensitive kernel     memory.

  - CVE-2007-2172     Thomas Graf reported a typo in the DECnet protocol     handler that could be used by a local attacker to     overrun an array via crafted packets, potentially     resulting in a Denial of Service (system crash). A     similar issue exists in the IPV4 protocol handler and     will be fixed in a subsequent update.

  - CVE-2007-2525     Florian Zumbiehl discovered a memory leak in the PPPOE     subsystem caused by releasing a socket before     PPPIOCGCHAN is called upon it. This could be used by a     local user to DoS a system by consuming all available     memory.

  - CVE-2007-3105     The PaX Team discovered a potential buffer overflow in     the random number generator which may permit local users     to cause a denial of service or gain additional     privileges. This issue is not believed to effect default     Debian installations where only root has sufficient     privileges to exploit it.

  - CVE-2007-3739     Adam Litke reported a potential local denial of service     (oops) on powerpc platforms resulting from unchecked VMA     expansion into address space reserved for hugetlb pages.

  - CVE-2007-3740     Steve French reported that CIFS filesystems with     CAP_UNIX enabled were not honoring a process' umask     which may lead to unintentionally relaxed permissions.

  - CVE-2007-3848     Wojciech Purczynski discovered that pdeath_signal was     not being reset properly under certain conditions which     may allow local users to gain privileges by sending     arbitrary signals to suid binaries.

  - CVE-2007-4133     Hugh Dickins discovered a potential local DoS (panic) in     hugetlbfs. A misconversion of hugetlb_vmtruncate_list to     prio_tree may allow local users to trigger a BUG_ON()     call in exit_mmap.

  - CVE-2007-4308     Alan Cox reported an issue in the aacraid driver that     allows unprivileged local users to make ioctl calls     which should be restricted to admin privileges.

  - CVE-2007-4573     Wojciech Purczynski discovered a vulnerability that can     be exploited by a local user to obtain superuser     privileges on x86_64 systems. This resulted from     improper clearing of the high bits of registers during     ia32 system call emulation. This vulnerability is     relevant to the Debian amd64 port as well as users of     the i386 port who run the amd64 linux-image flavour.

  - CVE-2007-5093     Alex Smith discovered an issue with the pwc driver for     certain webcam devices. If the device is removed while a     userspace application has it open, the driver will wait     for userspace to close the device, resulting in a     blocked USB subsystem. This issue is of low security     impact as it requires the attacker to either have     physical access to the system or to convince a user with     local access to remove the device on their behalf.

  - CVE-2007-6063     Venustech AD-LAB discovered a a buffer overflow in the     isdn ioctl handling, exploitable by a local user.

  - CVE-2007-6151     ADLAB discovered a possible memory overrun in the ISDN     subsystem that may permit a local user to overwrite     kernel memory by issuing ioctls with unterminated data.

  - CVE-2007-6206     Blake Frantz discovered that when a core file owned by a     non-root user exists, and a root-owned process dumps     core over it, the core file retains its original     ownership. This could be used by a local user to gain     access to sensitive information.

  - CVE-2007-6694     Cyrill Gorcunov reported a NULL pointer dereference in     code specific to the CHRP PowerPC platforms. Local users     could exploit this issue to achieve a Denial of Service     (DoS).

  - CVE-2008-0007     Nick Piggin of SuSE discovered a number of issues in     subsystems which register a fault handler for memory     mapped areas. This issue can be exploited by local users     to achieve a Denial of Service (DoS) and possibly     execute arbitrary code.

The following matrix lists additional packages that were rebuilt for compatibility with or to take advantage of this update :

                             Debian 3.1 (sarge)            kernel-image-2.6.8-alpha    2.6.8-17sarge1                kernel-image-2.6.8-amd64    2.6.8-17sarge1                kernel-image-2.6.8-hppa     2.6.8-7sarge1                 kernel-image-2.6.8-i386     2.6.8-17sarge1                kernel-image-2.6.8-ia64     2.6.8-15sarge1                kernel-image-2.6.8-m68k     2.6.8-5sarge1                 kernel-image-2.6.8-s390     2.6.8-6sarge1                 kernel-image-2.6.8-sparc    2.6.8-16sarge1                kernel-patch-powerpc-2.6.8  2.6.8-13sarge1                fai-kernels                 1.9.1sarge8

This kernel update fixes the following security problems :

CVE-2008-0007: Insufficient range checks in certain fault handlers could be used by local attackers to potentially read or write kernel memory.

CVE-2008-0001: Incorrect access mode checks could be used by local attackers to corrupt directory contents and so cause denial of service attacks or potentially execute code.

CVE-2007-5966: Integer overflow in the hrtimer_start function in kernel/hrtimer.c in the Linux kernel before 2.6.23.10 allows local users to execute arbitrary code or cause a denial of service (panic) via a large relative timeout value. NOTE: some of these details are obtained from third-party information.

CVE-2007-3843: The Linux kernel checked the wrong global variable for the CIFS sec mount option, which might allow remote attackers to spoof CIFS network traffic that the client configured for security signatures, as demonstrated by lack of signing despite sec=ntlmv2i in a SetupAndX request.

CVE-2007-2242: The IPv6 protocol allows remote attackers to cause a denial of service via crafted IPv6 type 0 route headers (IPV6_RTHDR_TYPE_0) that create network amplification between two routers.

CVE-2007-6417: The shmem_getpage function (mm/shmem.c) in Linux kernel 2.6.11 through 2.6.23 does not properly clear allocated memory in some rare circumstances, which might allow local users to read sensitive kernel data or cause a denial of service (crash).

CVE-2007-4308: The (1) aac_cfg_open and (2) aac_compat_ioctl functions in the SCSI layer ioctl path in aacraid in the Linux kernel did not check permissions for ioctls, which might have allowed local users to cause a denial of service or gain privileges.

CVE-2007-3740: The CIFS filesystem, when Unix extension support is enabled, does not honor the umask of a process, which allows local users to gain privileges.

CVE-2007-3848: The Linux kernel allowed local users to send arbitrary signals to a child process that is running at higher privileges by causing a setuid-root parent process to die, which delivers an attacker-controlled parent process death signal (PR_SET_PDEATHSIG).

This kernel update fixes the following security problems :

++ CVE-2007-3104: The sysfs_readdir function in the Linux kernel 2.6 allows local users to cause a denial of service (kernel OOPS) by dereferencing a NULL pointer to an inode in a dentry.

++ CVE-2007-4997: A 2 byte buffer underflow in the ieee80211 stack was fixed, which might be used by attackers in the local WLAN reach to crash the machine.

++ CVE-2007-3740: The CIFS filesystem, when Unix extension support is enabled, did not honor the umask of a process, which allowed local users to gain privileges.

++ CVE-2007-4573: It was possible for local user to become root by exploiting a bug in the IA32 system call emulation. This problem affects the x86_64 platform only, on all distributions.

This problem was fixed for regular kernels, but had not been fixed for the XEN kernels. This update fixes the problem also for the XEN kernels.

++ CVE-2007-4308: The (1) aac_cfg_open and (2) aac_compat_ioctl functions in the SCSI layer ioctl path in aacraid did not check permissions for ioctls, which might have allowed local users to cause a denial of service or gain privileges.

++ CVE-2007-3843: The Linux kernel checked the wrong global variable for the CIFS sec mount option, which might allow remote attackers to spoof CIFS network traffic that the client configured for security signatures, as demonstrated by lack of signing despite sec=ntlmv2i in a SetupAndX request.

++ CVE-2007-5904: Multiple buffer overflows in CIFS VFS in the Linux kernel allowed remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via long SMB responses that trigger the overflows in the SendReceive function.

This requires the attacker to mis-present / replace a CIFS server the client machine is connected to.

++ CVE-2007-6063: Buffer overflow in the isdn_net_setcfg function in isdn_net.c in the Linux kernel allowed local users to have an unknown impact via a crafted argument to the isdn_ioctl function.

Furthermore, this kernel catches up to the SLE 10 state of the kernel, with numerous additional fixes.

Updated kernel packages that fix several security issues and a bug in the Red Hat Enterprise Linux 3 kernel are now available.

This update has been rated as having important security impact by the Red Hat Security Response Team.

The kernel packages contain the Linux kernel, the core of any Linux operating system.

A flaw was found in the handling of process death signals. This allowed a local user to send arbitrary signals to the suid-process executed by that user. A successful exploitation of this flaw depends on the structure of the suid-program and its signal handling.
(CVE-2007-3848, Important)

A flaw was found in the IPv4 forwarding base. This allowed a local user to cause a denial of service. (CVE-2007-2172, Important)

A flaw was found where a corrupted executable file could cause cross-region memory mappings on Itanium systems. This allowed a local user to cause a denial of service. (CVE-2006-4538, Moderate)

A flaw was found in the stack expansion when using the hugetlb kernel on PowerPC systems. This allowed a local user to cause a denial of service. (CVE-2007-3739, Moderate)

A flaw was found in the aacraid SCSI driver. This allowed a local user to make ioctl calls to the driver that should be restricted to privileged users. (CVE-2007-4308, Moderate)

As well, these updated packages fix the following bug :

* a bug in the TCP header prediction code may have caused 'TCP:
Treason uncloaked!' messages to be logged. In certain situations this may have lead to TCP connections hanging or aborting.

Red Hat Enterprise Linux 3 users are advised to upgrade to these updated packages, which contain backported patches to resolve these issues.

A flaw was discovered in the PPP over Ethernet implementation. Local attackers could manipulate ioctls and cause kernel memory consumption leading to a denial of service. (CVE-2007-2525)

An integer underflow was discovered in the cpuset filesystem. If mounted, local attackers could obtain kernel memory using large file offsets while reading the tasks file. This could disclose sensitive data. (CVE-2007-2875)

Vilmos Nebehaj discovered that the SCTP netfilter code did not correctly validate certain states. A remote attacker could send a specially crafted packet causing a denial of service. (CVE-2007-2876)

Luca Tettamanti discovered a flaw in the VFAT compat ioctls on 64-bit systems. A local attacker could corrupt a kernel_dirent struct and cause a denial of service. (CVE-2007-2878)

A flaw in the sysfs_readdir function allowed a local user to cause a denial of service by dereferencing a NULL pointer. (CVE-2007-3104)

A buffer overflow was discovered in the random number generator. In environments with granular assignment of root privileges, a local attacker could gain additional privileges. (CVE-2007-3105)

A flaw was discovered in the usblcd driver. A local attacker could cause large amounts of kernel memory consumption, leading to a denial of service. (CVE-2007-3513)

Zhongling Wen discovered that the h323 conntrack handler did not correctly handle certain bitfields. A remote attacker could send a specially crafted packet and cause a denial of service.
(CVE-2007-3642)

A flaw was discovered in the CIFS mount security checking. Remote attackers could spoof CIFS network traffic, which could lead a client to trust the connection. (CVE-2007-3843)

It was discovered that certain setuid-root processes did not correctly reset process death signal handlers. A local user could manipulate this to send signals to processes they would not normally have access to. (CVE-2007-3848)

The Direct Rendering Manager for the i915 driver could be made to write to arbitrary memory locations. An attacker with access to a running X11 session could send a specially crafted buffer and gain root privileges. (CVE-2007-3851)

It was discovered that the aacraid SCSI driver did not correctly check permissions on certain ioctls. A local attacker could cause a denial of service or gain privileges. (CVE-2007-4308).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

A buffer overflow was discovered in the Moxa serial driver. Local attackers could execute arbitrary code and gain root privileges.
(CVE-2005-0504)

A flaw was discovered in the IPv6 stack's handling of type 0 route headers. By sending a specially crafted IPv6 packet, a remote attacker could cause a denial of service between two IPv6 hosts.
(CVE-2007-2242)

A flaw in the sysfs_readdir function allowed a local user to cause a denial of service by dereferencing a NULL pointer. (CVE-2007-3104)

A buffer overflow was discovered in the random number generator. In environments with granular assignment of root privileges, a local attacker could gain additional privileges. (CVE-2007-3105)

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Some vulnerabilities were discovered and corrected in the Linux 2.6 kernel :

A stack-based buffer overflow in the random number generator could allow local root users to cause a denial of service or gain privileges by setting the default wakeup threshold to a value greater than the output pool size (CVE-2007-3105).

The lcd_write function did not limit the amount of memory used by a caller, which allows local users to cause a denial of service (memory consumption) (CVE-2007-3513).

The decode_choice function allowed remote attackers to cause a denial of service (crash) via an encoded out-of-range index value for a choice field which triggered a NULL pointer dereference (CVE-2007-3642).

The Linux kernel allowed local users to send arbitrary signals to a child process that is running at higher privileges by causing a setuid-root parent process to die which delivered an attacker-controlled parent process death signal (PR_SET_PDEATHSIG) (CVE-2007-3848).

The aac_cfg_openm and aac_compat_ioctl functions in the SCSI layer ioctl patch in aacraid did not check permissions for ioctls, which might allow local users to cause a denial of service or gain privileges (CVE-2007-4308).

The IA32 system call emulation functionality, when running on the x86_64 architecture, did not zero extend the eax register after the 32bit entry path to ptrace is used, which could allow local users to gain privileges by triggering an out-of-bounds access to the system call table using the %RAX register (CVE-2007-4573).

In addition to these security fixes, other fixes have been included such as :

  - More NVidia PCI ids wre added

    - The 3w-9xxx module was updated to version 2.26.02.010

    - Fixed the map entry for ICH8

    - Added the TG3 5786 PCI id

    - Reduced the log verbosity of cx88-mpeg

Several local and remote vulnerabilities have been discovered in the Linux kernel that may lead to a denial of service or the execution of arbitrary code. The Common Vulnerabilities and Exposures project identifies the following problems :

  - CVE-2007-2172     Thomas Graf reported a typo in the IPv4 protocol handler     that could be used by a local attacker to overrun an     array via crafted packets, potentially resulting in a     Denial of Service (system crash). The DECnet counterpart     of this issue was already fixed in DSA-1356.

  - CVE-2007-2875     iDefense reported a potential integer underflow in the     cpuset filesystem which may permit local attackers to     gain access to sensitive kernel memory. This     vulnerability is only exploitable if the cpuset     filesystem is mounted.

  - CVE-2007-3105     The PaX Team discovered a potential buffer overflow in     the random number generator which may permit local users     to cause a denial of service or gain additional     privileges. This issue is not believed to effect default     Debian installations where only root has sufficient     privileges to exploit it.

  - CVE-2007-3843     A coding error in the CIFS subsystem permits the use of     unsigned messages even if the client has configured the     system to enforce signing by passing the sec=ntlmv2i     mount option. This may allow remote attackers to spoof     CIFS network traffic.

  - CVE-2007-4308     Alan Cox reported an issue in the aacraid driver that     allows unprivileged local users to make ioctl calls     which should be restricted to admin privileges.

These problems have been fixed in the stable distribution in version 2.6.18.dfsg.1-13etch2.

The following matrix lists additional packages that were rebuilt for compatibility with or to take advantage of this update :
