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-2013-1059 Chanam Park reported an issue in the Ceph distributed storage system. Remote users can cause a denial of service by sending a specially crafted auth_reply message. CVE-2013-2148 Dan Carpenter reported an information leak in the filesystem wide access notification subsystem (fanotify). Local users could gain access to sensitive kernel memory. CVE-2013-2164 Jonathan Salwan reported an information leak in the CD-ROM driver. A local user on a system with a malfunctioning CD-ROM drive could gain access to sensitive memory. CVE-2013-2232 Dave Jones and Hannes Frederic Sowa resolved an issue in the IPv6 subsystem. Local users could cause a denial of service by using an AF_INET6 socket to connect to an IPv4 destination. CVE-2013-2234 Mathias Krause reported a memory leak in the implementation of PF_KEYv2 sockets. Local users could gain access to sensitive kernel memory. CVE-2013-2237 Nicolas Dichtel reported a memory leak in the implementation of PF_KEYv2 sockets. Local users could gain access to sensitive kernel memory. CVE-2013-2851 Kees Cook reported an issue in the block subsystem. Local users with uid 0 could gain elevated ring 0 privileges. This is only a security issue for certain specially configured systems. CVE-2013-2852 Kees Cook reported an issue in the b43 network driver for certain Broadcom wireless devices. Local users with uid 0 could gain elevated ring 0 privileges. This is only a security issue for certain specially configured systems. CVE-2013-4162 Hannes Frederic Sowa reported an issue in the IPv6 networking subsystem. Local users can cause a denial of service (system crash). CVE-2013-4163 Dave Jones reported an issue in the IPv6 networking subsystem. Local users can cause a denial of service (system crash). This update also includes a fix for a regression in the Xen subsystem. For the stable distribution (wheezy), these problems has been fixed in version 3.2.46-1+deb7u1. The following matrix lists additional source packages that were rebuilt for compatibility with or to take advantage of this update: Debian 7.0 (wheezy) user-mode-linux 3.2-2um-1+deb7u2 We recommend that you upgrade your linux 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.
