Several vulnerabilities have been discovered in the Linux kernel that may lead to denial of service or privilege escalation. The Common Vulnerabilities and Exposures project identifies the following problems: Neil Horman discovered a missing fix from the e1000 network driver. A remote user may cause a denial of service by way of a kernel panic triggered by specially crafted frame sizes. Michael Tokarev discovered an issue in the r8169 network driver. Remote users on the same LAN may cause a denial of service by way of a kernel panic triggered by receiving a large size frame. Frank Filz discovered that local users may be able to execute files without execute permission when accessed via an nfs4 mount. Jeff Layton and Suresh Jayaraman fixed several buffer overflows in the CIFS filesystem which allow remote servers to cause memory corruption. Tavis Ormandy and Julien Tinnes discovered an issue with how the sendpage function is initialized in the proto_ops structure. Local users can exploit this vulnerability to gain elevated privileges.
