760529e5784a4c45d323b6b90d60c38cfaa4a399d95492fd1f96c65cfeea827bUbuntu Security Notice 3445-2 - USN-3445-1 fixed vulnerabilities in the Linux kernel for Ubuntu 14.04 LTS. This update provides the corresponding updates for the Linux Hardware Enablement kernel from Ubuntu 14.04 LTS for Ubuntu 12.04 ESM. Eyal Itkin discovered that the IP over IEEE 1394 implementation in the Linux kernel contained a buffer overflow when handling fragmented packets. A remote attacker could use this to possibly execute arbitrary code with administrative privileges. Various other issues were also addressed.

A remote attacker could use this to possibly execute arbitrary code with administrative privileges. Andrey Konovalov discovered that a divide-by-zero error existed in the TCP stack implementation in the Linux kernel. A local attacker could use this to cause a denial of service. Various other issues were also addressed.
41148c3875df1318c2d2413af391b6fecd0574d0356664d817900e15ef26bca7Several security issues were fixed in the kernel. Andrey Konovalov discovered that the AF_PACKET implementation in the Linux kernel did not properly validate certain block-size data. A local attacker could use this to cause a denial of service (system crash). Andrey Konovalov discovered a use-after-free vulnerability in the DCCP implementation in the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or possibly gain administrative privileges. Various other issues were also addressed.

A local attacker could use this to cause a denial of service. Andreas Gruenbacher and Jan Kara discovered that the filesystem implementation in the Linux kernel did not clear the setgid bit during a setxattr call. A local attacker could use this to possibly elevate group privileges. Various other issues were also addressed.

A local attacker could use this to cause a denial of service. It was discovered that the KVM implementation for x86/x86_64 in the Linux kernel could dereference a null pointer. An attacker in a guest virtual machine could use this to cause a denial of service in the KVM host. Various other issues were also addressed.

A local attacker could use this to expose sensitive information. It was discovered that the Video For Linux Two implementation in the Linux kernel did not properly handle multiple planes when processing a VIDIOC_DQBUF ioctl. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. Various other issues were also addressed.
