Tenable has extracted the preceding description block directly from the Oracle Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

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)

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.

This kernel update fixes the following security problems :

  - 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-2007-2242)

    The default is that RH0 is disabled now. To adjust this,     write to the file /proc/net/accept_source_route6.

  - The random number feature in the Linux kernel 2.6 (1)     did not properly seed pools when there is no entropy, or     (2) used an incorrect cast when extracting entropy,     which might have caused the random number generator to     provide the same values after reboots on systems without     an entropy source. (CVE-2007-2453)

  - A NULL pointer dereference in SCTP connection tracking     could be caused by a remote attacker by sending     specially crafted packets. Note that this requires SCTP     set-up and active to be exploitable. (CVE-2007-2876)

  - Stack-based buffer overflow in the random number     generator (RNG) implementation in the Linux kernel     before 2.6.22 might 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, which triggers writing random numbers     to the stack by the pool transfer function involving     'bound check ordering'. (CVE-2007-3105)

    Since this value can only be changed by a root user,     exploitability is low.

  - The signal handling in the Linux kernel, when run on     PowerPC systems using HTX, allows local users to cause a     denial of service via unspecified vectors involving     floating point corruption and concurrency.
    (CVE-2007-3107)

  - Memory leak in the PPP over Ethernet (PPPoE) socket     implementation in the Linux kernel allowed local users     to cause a denial of service (memory consumption) by     creating a socket using connect, and releasing it before     the PPPIOCGCHAN ioctl is initialized. (CVE-2007-2525)

  - The lcd_write function in drivers/usb/misc/usblcd.c in     the Linux kernel did not limit the amount of memory used     by a caller, which allowed local users to cause a denial     of service (memory consumption). (CVE-2007-3513)

  - A local attacker could send a death signal to a setuid     root program under certain conditions, potentially     causing unwanted behaviour in this program.
    (CVE-2007-3848)

  - On machines with a Intel i965 based graphics card local     users with access to the direct rendering devicenode     could overwrite memory on the machine and so gain root     privileges. (CVE-2007-3851)

  - Fixed a denial of service possibility where a local     attacker with access to a pwc camera device could hang     the USB subsystem. [#302194]

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.

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-2007-1353     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-2007-2453     A couple of issues with random number generation were     discovered. Slightly less random numbers resulted from     hashing a subset of the available entropy. Zero-entropy     systems were seeded with the same inputs at boot time,     resulting in repeatable series of random numbers.

  - 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-2007-2876     Vilmos Nebehaj discovered a NULL pointer dereference     condition in the netfilter subsystem. This allows remote     systems which communicate using the SCTP protocol to     crash a system by creating a connection with an unknown     chunk type.

  - CVE-2007-3513     Oliver Neukum reported an issue in the usblcd driver     which, by not limiting the size of write buffers,     permits local users with write access to trigger a DoS     by consuming all available memory.

  - CVE-2007-3642     Zhongling Wen reported an issue in nf_conntrack_h323     where the lack of range checking may lead to NULL     pointer dereferences. Remote attackers could exploit     this to create a DoS condition (system crash).

  - 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-2007-3851     Dave Airlie reported that Intel 965 and above chipsets     have relocated their batch buffer security bits. Local X     server users may exploit this to write user data to     arbitrary physical memory addresses.

These problems have been fixed in the stable distribution in version 2.6.18.dfsg.1-13etch1.

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

                    Debian 4.0 (etch)    fai-kernels        1.17+etch4           user-mode-linux    2.6.18-1um-2etch3

This kernel update brings the kernel to the one shipped with SLES 10 Service Pack 1 and also fixes the following security problems:

- 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. 

  The default is that RH0 is disabled now. To adjust this, write to the file /proc/net/accept_source_route6.

- CVE-2007-2453: The random number feature in the Linux   kernel 2.6 (1) did not properly seed pools when there is   no entropy, or (2) used an incorrect cast when extracting   entropy, which might have caused the random number   generator to provide the same values after reboots on   systems without an entropy source.

- CVE-2007-2876: A NULL pointer dereference in SCTP   connection tracking could be caused by a remote attacker   by sending specially crafted packets. Note that this   requires SCTP set-up and active to be exploitable.

- CVE-2007-3105: Stack-based buffer overflow in the random   number generator (RNG) implementation in the Linux kernel   before 2.6.22 might 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, which triggers writing random numbers   to the stack by the pool transfer function involving   'bound check ordering'.

  Since this value can only be changed by a root user, exploitability is low.

- CVE-2007-3107: The signal handling in the Linux kernel,   when run on PowerPC systems using HTX, allows local users   to cause a denial of service via unspecified vectors   involving floating point corruption and concurrency.

- CVE-2007-2525: Memory leak in the PPP over Ethernet   (PPPoE) socket implementation in the Linux kernel allowed   local users to cause a denial of service (memory   consumption) by creating a socket using connect, and   releasing it before the PPPIOCGCHAN ioctl is initialized.

- CVE-2007-3513: The lcd_write function in   drivers/usb/misc/usblcd.c in the Linux kernel did not   limit the amount of memory used by a caller, which   allowed local users to cause a denial of service (memory   consumption).

- CVE-2007-3851: On machines with a Intel i965 based   graphics card local users with access to the direct   rendering devicenode could overwrite memory on the   machine and so gain root privileges.

This kernel is not compatible to the previous SUSE Linux 10.1 kernel, so the Kernel Module Packages will need to be updated.

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.

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

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 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 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.

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

A flaw was discovered in dvb ULE decapsulation. A remote attacker could send a specially crafted message and cause a denial of service.
(CVE-2006-4623)

The compat_sys_mount function allowed local users to cause a denial of service when mounting a smbfs filesystem in compatibility mode.
(CVE-2006-7203)

The Omnikey CardMan 4040 driver (cm4040_cs) did not limit the size of buffers passed to read() and write(). A local attacker could exploit this to execute arbitrary code with kernel privileges. (CVE-2007-0005)

Due to an variable handling flaw in the ipv6_getsockopt_sticky() function a local attacker could exploit the getsockopt() calls to read arbitrary kernel memory. This could disclose sensitive data.
(CVE-2007-1000)

Ilja van Sprundel discovered that Bluetooth setsockopt calls could leak kernel memory contents via an uninitialized stack buffer. A local attacker could exploit this flaw to view sensitive kernel information.
(CVE-2007-1353)

A flaw was discovered in the handling of netlink messages. Local attackers could cause infinite recursion leading to a denial of service. (CVE-2007-1861)

The random number generator was hashing a subset of the available entropy, leading to slightly less random numbers. Additionally, systems without an entropy source would be seeded with the same inputs at boot time, leading to a repeatable series of random numbers.
(CVE-2007-2453)

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 was discovered in the cluster manager. A remote attacker could connect to the DLM port and block further DLM operations.
(CVE-2007-3380)

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).
