46213a5d7256ccc486e09644da5d4a3741fa2506819b7e2725344f3ca8bb31cbUbuntu Security Notice 3583-2 - USN-3583-1 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. It was discovered that an out-of-bounds write vulnerability existed in the Flash-Friendly File System in the Linux kernel. An attacker could construct a malicious file system that, when mounted, could cause a denial of service or possibly execute arbitrary code. Various other issues were also addressed.
25ede7de1d2b86456063e72f35df6f1394e7346ba13182c33a91a7d898707f22Ubuntu Security Notice 3583-1 - It was discovered that an out-of-bounds write vulnerability existed in the Flash-Friendly File System in the Linux kernel. An attacker could construct a malicious file system that, when mounted, could cause a denial of service or possibly execute arbitrary code. It was discovered that a race condition leading to a use-after-free vulnerability existed in the ALSA PCM subsystem of the Linux kernel. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. Various other issues were also addressed.

This update provides the corresponding updates for the Linux Hardware Enablement kernel from Ubuntu 16.04 LTS for Ubuntu 14.04 LTS. Mohamed Ghannam discovered that the IPv4 raw socket implementation in the Linux kernel contained a race condition leading to uninitialized pointer usage. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. Various other issues were also addressed.

A local attacker could use this to cause a denial of service or possibly execute arbitrary code. Laurent Guerby discovered that the mbcache feature in the ext2 and ext4 filesystems in the Linux kernel improperly handled xattr block caching. A local attacker could use this to cause a denial of service. Various other issues were also addressed.

A local attacker in a guest VM could use this to cause a denial of service or possibly execute arbitrary code in the host OS. It was discovered that on the PowerPC architecture, the kernel did not properly sanitize the signal stack when handling sigreturn. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. Various other issues were also addressed.
