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

  - CVE-2009-4895     Kyle Bader reported an issue in the tty subsystem that     allows local users to create a denial of service (NULL     pointer dereference).

  - CVE-2010-2226     Dan Rosenberg reported an issue in the xfs filesystem     that allows local users to copy and read a file owned by     another user, for which they only have write     permissions, due to a lack of permission checking in the     XFS_SWAPEXT ioctl.

  - CVE-2010-2240     Rafal Wojtczuk reported an issue that allows users to     obtain escalated privileges. Users must already have     sufficient privileges to execute or connect clients to     an Xorg server.

  - CVE-2010-2248     Suresh Jayaraman discovered an issue in the CIFS     filesystem. A malicious file server can set an incorrect     'CountHigh' value, resulting in a denial of service     (BUG_ON() assertion).

  - CVE-2010-2521     Neil Brown reported an issue in the NFSv4 server code. A     malicious client could trigger a denial of service     (Oops) on a server due to a bug in the read_buf()     routine.

  - CVE-2010-2798     Bob Peterson reported an issue in the GFS2 file system.
    A file system user could cause a denial of service     (Oops) via certain rename operations.

  - CVE-2010-2803     Kees Cook reported an issue in the DRM (Direct Rendering     Manager) subsystem. Local users with sufficient     privileges (local X users or members of the 'video'     group on a default Debian install) could acquire access     to sensitive kernel memory.

  - CVE-2010-2959     Ben Hawkes discovered an issue in the AF_CAN socket     family. An integer overflow condition may allow local     users to obtain elevated privileges.

  - CVE-2010-3015     Toshiyuki Okajima reported an issue in the ext4     filesystem. Local users could trigger a denial of     service (BUG assertion) by generating a specific set of     filesystem operations.

This update also includes fixes a regression introduced by a previous update. See the referenced Debian bug page for details.

Gael Delalleu, Rafal Wojtczuk, and Brad Spengler discovered that the memory manager did not properly handle when applications grow stacks into adjacent memory regions. A local attacker could exploit this to gain control of certain applications, potentially leading to privilege escalation, as demonstrated in attacks against the X server.
(CVE-2010-2240)

Kees Cook discovered that under certain situations the ioctl subsystem for DRM did not properly sanitize its arguments. A local attacker could exploit this to read previously freed kernel memory, leading to a loss of privacy. (CVE-2010-2803)

Ben Hawkes discovered an integer overflow in the Controller Area Network (CAN) subsystem when setting up frame content and filtering certain messages. An attacker could send specially crafted CAN traffic to crash the system or gain root privileges. (CVE-2010-2959).
