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. CVE-2013-2929 Vasily Kulikov discovered that a flaw in the get_dumpable() function of the ptrace subsytsem could lead to information disclosure. Only systems with the fs.suid_dumpable sysctl set to a non-default value of '2' are vulnerable. CVE-2013-4162 Hannes Frederic Sowa discovered that incorrect handling of IPv6 sockets using the UDP_CORK option could result in denial of service. CVE-2013-4299 Fujitsu reported an issue in the device-mapper subsystem. Local users could gain access to sensitive kernel memory. CVE-2013-4345 Stephan Mueller found in bug in the ANSI pseudo random number generator which could lead to the use of less entropy than expected. CVE-2013-4512 Nico Golde and Fabian Yamaguchi reported an issue in the user mode linux port. A buffer overflow condition exists in the write method for the /proc/exitcode file. Local users with sufficient privileges allowing them to write to this file could gain further elevated privileges. CVE-2013-4587 Andrew Honig of Google reported an issue in the KVM virtualization subsystem. A local user could gain elevated privileges by passing a large vcpu_id parameter. CVE-2013-6367 Andrew Honig of Google reported an issue in the KVM virtualization subsystem. A divide-by-zero condition could allow a guest user to cause a denial of service on the host (crash). CVE-2013-6380 Mahesh Rajashekhara reported an issue in the aacraid driver for storage products from various vendors. Local users with CAP_SYS_ADMIN privileges could gain further elevated privileges. CVE-2013-6381 Nico Golde and Fabian Yamaguchi reported an issue in the Gigabit Ethernet device support for s390 systems. Local users could cause a denial of service or gain elevated privileges via the SIOC_QETH_ADP_SET_SNMP_CONTROL ioctl. CVE-2013-6382 Nico Golde and Fabian Yamaguchi reported an issue in the XFS filesystem. Local users with CAP_SYS_ADMIN privileges could gain further elevated privileges. CVE-2013-6383 Dan Carpenter reported an issue in the aacraid driver for storage devices from various vendors. A local user could gain elevated privileges due to a missing privilege level check in the aac_compat_ioctl function. CVE-2013-7263 CVE-2013-7264 CVE-2013-7265 mpb reported an information leak in the recvfrom, recvmmsg and recvmsg system calls. A local user could obtain access to sensitive kernel memory. CVE-2013-7339 Sasha Levin reported an issue in the RDS network protocol over Infiniband. A local user could cause a denial of service condition. CVE-2014-0101 Nokia Siemens Networks reported an issue in the SCTP network protocol subsystem. Remote users could cause a denial of service (NULL pointer dereference). CVE-2014-1444 Salva Peiro reported an issue in the FarSync WAN driver. Local users with the CAP_NET_ADMIN capability could gain access to sensitive kernel memory. CVE-2014-1445 Salva Peiro reported an issue in the wanXL serial card driver. Local users could gain access to sensitive kernel memory. CVE-2014-1446 Salva Peiro reported an issue in the YAM radio modem driver. Local users with the CAP_NET_ADMIN capability could gain access to sensitive kernel memory. CVE-2014-1874 Matthew Thode reported an issue in the SELinux subsystem. A local user with CAP_MAC_ADMIN privileges could cause a denial of service by setting an empty security context on a file. CVE-2014-2039 Martin Schwidefsky reported an issue on s390 systems. A local user could cause a denial of service (kernel oops) by executing an application with a linkage stack instruction. CVE-2014-2523 Daniel Borkmann provided a fix for an issue in the nf_conntrack_dccp module. Remote users could cause a denial of service (system crash) or potentially gain elevated privileges. 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-linux 2.6.32-1um-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.
