USN-3053-1: Linux kernel (Vivid HWE) vulnerabilities Ubuntu Security Notice USN-3053-1 10th August, 2016 linux-lts-vivid 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-vivid – Linux hardware enablement kernel from Vivid for Trusty Details A missing permission check when settings ACLs was discovered in nfsd. Alocal user could exploit this flaw to gain access to any file by setting anACL. (CVE-2016-1237) 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 cause adenial [ more… ]

USN-3054-1: Linux kernel (Xenial HWE) vulnerabilities Ubuntu Security Notice USN-3054-1 10th August, 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 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 [ more… ]
