Threat Level:
5/10
Description:Resources exhaustion on data decompression in png_decompress_chunk().
Affected:libpng : libpng 1.2
 libpng : libpng 1.0
 libpng : libpng 1.4
CVE:CVE-2010-0205 (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.)
