USN-3146-2: Linux kernel (Xenial HWE) vulnerabilities Ubuntu Security Notice USN-3146-2 30th November, 2016 linux-lts-xenial vulnerabilities A security issue affects these releases of Ubuntu and its derivatives: Ubuntu 14.04 LTS Summary Several security issues were fixed in the kernel. Software description linux-lts-xenial – Linux hardware enablement kernel from Xenial for Trusty Details USN-3146-1 fixed vulnerabilities in the Linux kernel for Ubuntu 16.04LTS. This update provides the corresponding updates for the LinuxHardware Enablement (HWE) kernel from Ubuntu 16.04 LTS for Ubuntu14.04 LTS. It was discovered that the __get_user_asm_ex implementation in the Linuxkernel for x86/x86_64 contained extended asm statements that wereincompatible with the exception table. A local attacker could use this togain administrative privileges. (CVE-2016-9644) Andreas Gruenbacher and Jan Kara discovered that the filesystemimplementation in the Linux kernel did not clear the setgid bit during asetxattr call. A local attacker could use this [ more… ]
