USN-3055-1: Linux kernel vulnerabilities Ubuntu Security Notice USN-3055-1 10th August, 2016 linux vulnerabilities A security issue affects these releases of Ubuntu and its derivatives: Ubuntu 16.04 LTS Summary Several security issues were fixed in the kernel. Software description linux – Linux kernel Details Ben Hawkes discovered an integer overflow in the Linux netfilterimplementation. On systems running 32 bit kernels, a local unprivilegedattacker could use this to cause a denial of service (system crash) orpossibly execute arbitrary code with administrative privileges.(CVE-2016-3135) It was discovered that the keyring implementation in the Linux kernel didnot ensure a data structure was initialized before referencing it after anerror condition occurred. A local attacker could use this to cause a denialof service (system crash). (CVE-2016-4470) Sasha Levin discovered that a use-after-free existed in the percpuallocator in the Linux kernel. A local attacker could use this to [ more… ]
