Mandriva Linux Security Advisory : libpng (MDVSA-2010:063)
high Nessus Plugin ID 45124
Language:
Synopsis
The remote Mandriva Linux host is missing one or more security updates.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.
