http://security.gentoo.org/

Severity:	normal
Title:	OpenAFS: Arbitrary code execution
Date:	01/16/2011
Bugs:	#265538
ID:	201101-05

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	Architecture(s)
net-fs/openafs	< 1.4.9	>= 1.4.9	All supported architectures

Description

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).
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 vulnerabilities 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"
