Several vulnerabilities have been discovered in the Linux kernel that may lead to a denial of service, or privilege escalation. The Common Vulnerabilities and Exposures project identifies the following problems: 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. Jan Beulich discovered an issue in Xen where local guest users may cause a denial of service (oops). This update also fixes a regression introduced by the fix for CVE-2009-1184 in 2.6.26-15lenny3. This prevents a boot time panic on systems with SELinux enabled.
