 Mandriva Linux Security Advisory                         MDVSA-2010:063
 http://www.mandriva.com/security/
 _______________________________________________________________________

 Package : libpng
 Date    : March 22, 2010
 Affected: 2008.0, Corporate 4.0, Multi Network Firewall 2.0
 _______________________________________________________________________

 Problem Description:

 Multiple vulnerabilities has been found and corrected in libpng:
 
 libpng before 1.2.37 does not properly parse 1-bit interlaced images
 with width values that are not divisible by 8, which causes libpng
 to include uninitialized bits in certain rows of a PNG file and
 might allow remote attackers to read portions of sensitive memory
 via out-of-bounds pixels in the file (CVE-2009-2042).
 
 The png_decompress_chunk function in pngrutil.c in libpng 1.0.x before
 1.0.53, 1.2.x before 1.2.43, and 1.4.x before 1.4.1 does not properly
 handle compressed ancillary-chunk data that has a disproportionately
 large uncompressed representation, which allows remote attackers to
 cause a denial of service (memory and CPU consumption, and application
 hang) via a crafted PNG file, as demonstrated by use of the deflate
 compression method on data composed of many occurrences of the same
 character, related to a decompression bomb attack (CVE-2010-0205).
 
 Packages for 2008.0 are provided for Corporate Desktop 2008.0
 customers.
 
 The updated packages have been patched to correct these issues.
