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"
