libpng png_decompress_chunk() function denial of service
|libpng-pngdecompresschunk-dos (56661)||Medium Risk|
libpng is vulnerable to a denial of service, caused by an error in the png_decompress_chunk() function. By persuading a victim to open a specially-crafted PNG file containing highly compressed ancillary chunks, a remote attacker could exploit this vulnerability to cause the affected application to hang.
Denial of Service
Upgrade to the latest version of libpng (1.0.53, 1.2.43, 1.4.1 or later), available from the PNG Reference Library: libpng Web site. See References.
For other distributions:
Apply the appropriate update for your system. See References.

- 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.
