82b374fa56da7125a045baa707e307b1Ubuntu 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.
31d9ad4299f2ef96b20bed7917d8b10eUbuntu 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.
72f5ce45fa98483fb5383129af775873Ubuntu Security Notice 3582-2 - USN-3582-1 fixed vulnerabilities in the Linux kernel for Ubuntu 16.04 LTS. 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.
587cb9ef4fb21c7488d73d97033aa051Ubuntu Security Notice 3582-1 - 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. 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.
7c867a8643606e86327bf1724e3a46daUbuntu Security Notice 3487-1 - It was discovered that the KVM subsystem in the Linux kernel did not properly keep track of nested levels in guest page tables. 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.
