Double free vulnerability in the Rx server process in OpenAFS 1.4.14, 1.4.12, 1.4.7, and possibly other versions allows remote attackers to cause a denial of service and execute arbitrary code via unknown vectors.

The remote host is affected by the vulnerability described in GLSA-201404-05 (OpenAFS: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in OpenAFS. Please review       the CVE identifiers referenced below for details.
  Impact :

    An attacker could potentially execute arbitrary code with the       permissions of the user running the AFS server, cause a Denial of Service       condition, or gain access to sensitive information. Additionally, an       attacker could compromise a cell&rsquo;s private key, allowing them to       impersonate any user in the cell.
  Workaround :

    There is no known workaround at this time.

Double free vulnerability in the Rx server process in OpenAFS 1.4.14, 1.4.12, 1.4.7, and possibly other versions allows remote attackers to cause a denial of service and execute arbitrary code via unknown vectors. (CVE-2011-0430)

The afs_linux_lock function in afs/LINUX/osi_vnodeops.c in the kernel module in OpenAFS 1.4.14, 1.4.12, 1.4.7, and possibly other versions does not properly handle errors, which allows attackers to cause a denial of service via unknown vectors. (CVE-2011-0431)

This update will also bring all the SL4 and SL5 openafs versions up to the same version.

Two vulnerabilities were discovered the distributed filesystem AFS :

  - CVE-2011-0430     Andrew Deason discovered that a double free in the Rx     server process could lead to denial of service or the     execution of arbitrary code.

  - CVE-2011-0431     It was discovered that insufficient error handling in     the kernel module could lead to denial of service.
