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-2013-0160 vladz reported a timing leak with the /dev/ptmx character device. A local user could use this to determine sensitive information such as password length. CVE-2013-1796 Andrew Honig of Google reported an issue in the KVM subsystem. A user in a guest operating system could corrupt kernel memory, resulting in a denial of service. CVE-2013-1929 Oded Horovitz and Brad Spengler reported an issue in the device driver for Broadcom Tigon3 based gigabit Ethernet. Users with the ability to attach untrusted devices can create an overflow condition, resulting in a denial of service or elevated privileges. CVE-2013-1979 Andy Lutomirski reported an issue in the socket level control message processing subsystem. Local users maybe able to gain elevated privileges. CVE-2013-2015 Theodore Ts"o provided a fix for an issue in the ext4 filesystem. Local users with the ability to mount a specially crafted filesystem can cause a denial of service . CVE-2013-2094 Tommie Rantala discovered an issue in the perf subsystem. An out-of-bounds access vulnerability allows local users to gain elevated privileges. CVE-2013-3076 Mathias Krauss discovered an issue in the userspace interface for hash algorithms. Local users can gain access to sensitive kernel memory.
