Summary

Several vulnerabilities have been discovered in the Linux kernel that may lead to a denial of service, information leak or privilege escalation. The Common Vulnerabilities and Exposures project identifies the following problems: CVE-2013-0343 George Kargiotakis reported an issue in the temporary address handling of the IPv6 privacy extensions. Users on the same LAN can cause a denial of service or obtain access to sensitive information by sending router advertisement messages that cause temporary address generation to be disabled. CVE-2013-2147 Dan Carpenter reported issues in the cpqarray driver for Compaq Smart2 Controllers and the cciss driver for HP Smart Array controllers allowing users to gain access to sensitive kernel memory. CVE-2013-2889 Kees Cook discovered missing input sanitization in the HID driver for Zeroplus game pads that could lead to a local denial of service. CVE-2013-2893 Kees Cook discovered that missing input sanitization in the HID driver for various Logitech force feedback devices could lead to a local denial of service. Description truncated. Please see the references for more information.

Solution

Solution

For the oldstable distribution (squeeze), this problem has been fixed in version 2.6.32-48squeeze5. The following matrix lists additional source packages that were rebuilt for compatibility with or to take advantage of this update: ?Debian 6.0 (squeeze)user-mode-linux2.6.32-1um-4+48squeeze5 We recommend that you upgrade your linux-2.6 and user-mode-linux packages. Note: Debian carefully tracks all known security issues across every linux kernel package in all releases under active security support. However, given the high frequency at which low-severity security issues are discovered in the kernel and the resource requirements of doing an update, updates for lower priority issues will normally not be released for all kernels at the same time. Rather, they will be released in a staggered or leap-frog fashion.
