Insight
Insight
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: CVE-2009-1630 Frank Filz discovered that local users may be able to execute files without execute permission when accessed via an nfs4 mount. CVE-2009-1633 Jeff Layton and Suresh Jayaraman fixed several buffer overflows in the CIFS filesystem which allow remote servers to cause memory corruption. CVE-2009-1758 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. For the stable distribution (lenny), these problems have been fixed in version 2.6.26-15lenny3. For the oldstable distribution (etch), these problems, where applicable, will be fixed in future updates to linux-2.6 and linux-2.6.24. We recommend that you upgrade your linux-2.6 and user-mode-linux
