-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - ---------------------------------------------------------------------- Debian Security Advisory DSA-2766-1 security@xxxxxxxxxx http://www.debian.org/security/ Dann Frazier September 27, 2013 http://www.debian.org/security/faq - ---------------------------------------------------------------------- Package : linux-2.6 Vulnerability : privilege escalation/denial of service/information leak Problem type : local/remote Debian-specific: no CVE Id(s) : CVE-2013-2141 CVE-2013-2164 CVE-2013-2206 CVE-2013-2232 CVE-2013-2234 CVE-2013-2237 CVE-2013-2239 CVE-2013-2851 CVE-2013-2852 CVE-2013-2888 CVE-2013-2892 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-2013-2141 Emese Revfy provided a fix for an information leak in the tkill and tgkill system calls. A local user on a 64-bit system maybe able to gain access to sensitive memory contents. 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-2013-2206 Karl Heiss reported an issue in the Linux SCTP implementation. A remote user could cause a denial of service (system crash). 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-2013-2239 Jonathan Salwan discovered multiple memory leaks in the openvz kernel flavor. 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-2013-2888 Kees Cook reported an issue in the HID driver subsystem. A local user, with the ability to attach a device, could cause a denial of service (system crash). CVE-2013-2892 Kees Cook reported an issue in the pantherlord HID device driver. Local users with the ability to attach a device could cause a denial of service or possibly gain elevated privileges. For the oldstable distribution (squeeze), this problem has been fixed in version 2.6.32-48squeeze4. 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-linux 2.6.32-1um-4+48squeeze4 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.
