"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."
