Mandriva Linux Security Advisory MDKSA-2006:213
http://www.mandriva.com/security/

Package : chromium
Date : November 16, 2006
Affected: 2007.0, Corporate 3.0
_______________________________________________________________________

Problem Description:

Chromium is an OpenGL-based shoot them up game with fine graphics. It
is built with a private copy of libpng, and as such could be
susceptible to some of the same vulnerabilities:

Buffer overflow in the png_decompress_chunk function in pngrutil.c in
libpng before 1.2.12 allows context-dependent attackers to cause a
denial of service and possibly execute arbitrary code via unspecified
vectors related to "chunk error processing," possibly involving the
"chunk_name". (CVE-2006-3334)

It is questionable whether this issue is actually exploitable, but the
patch to correct the issue has been included in versions lt; 1.2.12.

In addition, an patch to address several old vulnerabilities has been
applied to this build. (CAN-2002-1363, CAN-2004-0421, CAN-2004-0597,
CAN-2004-0598, CAN-2004-0599)

Packages have been patched to correct these issues.
