SUSE Linux Security Advisory: SUSE-SR:2010:012

Severity CVSS Published Added Modified
8 (AV:N/AC:L/Au:N/C:N/I:N/A:C) March 02, 2010 December 11, 2013 November 16, 2014

Description

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.
