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

  - CVE-2010-2963     Kees Cook discovered an issue in the v4l 32-bit     compatibility layer for 64-bit systems that allows local     users with /dev/video write permission to overwrite     arbitrary kernel memory, potentially leading to a     privilege escalation. On Debian systems, access to     /dev/video devices is restricted to members of the     'video' group by default.

  - CVE-2010-3067     Tavis Ormandy discovered an issue in the io_submit     system call. Local users can cause an integer overflow     resulting in a denial of service.

    Local users with permission to open /dev/pktcdvd/control     can obtain the contents of sensitive kernel memory or     cause a denial of service. By default on Debian systems,     this access is restricted to members of the group     'cdrom'.

  - CVE-2010-3442     Dan Rosenberg discovered an issue in the ALSA sound     system. Local users with permission to open     /dev/snd/controlC0 can create an integer overflow     condition that causes a denial of service. By default on     Debian systems, this access is restricted to members of     the group 'audio'.

  - CVE-2010-3448     Dan Jacobson reported an issue in the thinkpad-acpi     driver. On certain Thinkpad systems, local users can     cause a denial of service (X.org crash) by reading     /proc/acpi/ibm/video.

  - CVE-2010-3848     Nelson Elhage discovered an issue in the Econet     protocol. Local users can cause a stack overflow     condition with large msg->msgiovlen values that can     result in a denial of service or privilege escalation.

  - CVE-2010-3849     Nelson Elhage discovered an issue in the Econet     protocol. Local users can cause a denial of service     (oops) if a NULL remote addr value is passed as a     parameter to sendmsg().

  - CVE-2010-3850     Nelson Elhage discovered an issue in the Econet     protocol. Local users can assign econet addresses to     arbitrary interfaces due to a missing capabilities     check.

  - CVE-2010-3858     Brad Spengler reported an issue in the setup_arg_pages()     function. Due to a bounds-checking failure, local users     can create a denial of service (kernel oops).

  - CVE-2010-3859     Dan Rosenberg reported an issue in the TIPC protocol.
