Synopsis ========
The cache manager of OpenAFS contains several bugs resulting in remote execution of arbitrary code.
Background ==========
OpenAFS is a distributed file system.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-fs/openafs < 1.4.9 >= 1.4.9
Description ===========
Two vulnerabilites were discovered:
* Simon Wilkinson discovered from a bug report by Toby Blake that the cache manager of OpenAFS contains a heap-based buffer overflow which is related to the use of the ERR_PTR macro (CVE-2009-1250).
* A pointer dereference bug when using XDR arrays was discovered by Simon Wilkinson, with assistance from Derrick Brashear and Jeffrey Altman. (CVE-2009-1251).
Impact ======
The vulnerabilites might allow remote unauthenticated attackers to cause a Denial of Service (system crash) and possibly execute arbitrary code.
Workaround ==========
There is no known workaround at this time.
Resolution ==========
All OpenAFS users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=net-fs/openafs-1.4.9"
