Authored by Ubuntu | Site security.ubuntu.com

Ubuntu Security Notice 3776-2 - USN-3776-1 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. Jann Horn discovered that the vmacache subsystem did not properly handle sequence number overflows, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service or execute arbitrary code. Various other issues were also addressed.
