|Gentoo Linux Security Advisory
Title: OpenAFS: Arbitrary code execution (GLSA 201101-05)
Date: January 16, 2011
The cache manager of OpenAFS contains several bugs resulting in remote
execution of arbitrary code.
OpenAFS is a distributed file system.
Vulnerable: < 1.4.9
Unaffected: >= 1.4.9
Architectures: All supported architectures
Two vulnerabilities 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).
pointer dereference bug when using XDR arrays was discovered by Simon
Wilkinson, with assistance from Derrick Brashear and Jeffrey Altman.
The vulnerabilities might allow remote unauthenticated attackers to
cause a Denial of Service (system crash) and possibly execute arbitrary
There is no known workaround at this time.
All OpenAFS users should upgrade to the latest version:
|# emerge --sync
# emerge --ask --oneshot --verbose ">=net-fs/openafs-1.4.9"
