 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 < 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.
