The Linux kernel before 2.6.23-rc1 checks 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.

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.

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

The remote Oracle Linux 5 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2007-0705 advisory.

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)

Updated kernel packages that fix various security issues in the Red Hat Enterprise Linux 5 kernel are now available.

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

The Linux kernel handles the basic functions of the operating system.

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

* a flaw in the DRM driver for Intel graphics cards that allowed a local user to access any part of the main memory. To access the DRM functionality a user must have access to the X server which is granted through the graphical login. This also only affected systems with an Intel 965 or later graphic chipset. (CVE-2007-3851, Important)

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

* a flaw in the connection tracking support for SCTP that allowed a remote user to cause a denial of service by dereferencing a NULL pointer. (CVE-2007-2876, Important)

* flaw in the CIFS filesystem which could cause the umask values of a process to not be honored. This affected CIFS filesystems where the Unix extensions are supported. (CVE-2007-3740, Important)

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

* a flaw in the ISDN CAPI subsystem that allowed a remote user to cause a denial of service or potential remote access. Exploitation would require the attacker to be able to send arbitrary frames over the ISDN network to the victim's machine. (CVE-2007-1217, Moderate)

* a flaw in the cpuset support that allowed a local user to obtain sensitive information from kernel memory. To exploit this the cpuset filesystem would have to already be mounted. (CVE-2007-2875, Moderate)

* a flaw in the CIFS handling of the mount option 'sec=' that didn't enable integrity checking and didn't produce any error message.
(CVE-2007-3843, Low)

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

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.

This kernel update is a respin of a previous one that broke CPUFREQ support (bug 357598).

Previous changes :

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-2007-6417: 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).

This kernel update brings the kernel to version 2.6.22.16 and 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-2007-6417: 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-2007-2242: 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).

CVE-2007-4997: Integer underflow in the ieee80211_rx function in net/ieee80211/ieee80211_rx.c in the Linux kernel allowed remote attackers to cause a denial of service (crash) via a crafted SKB length value in a runt IEEE 802.11 frame when the IEEE80211_STYPE_QOS_DATA flag is set, aka an 'off-by-two error.'

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.

CVE-none-yet: A failed change_hat call can result in an apparmored task becoming unconfined (326546).

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-2007-5904: 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.

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.

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.
