The vulnerability is caused due to the library using large amount of CPU and memory resources when processing certain highly compressed ancillary chunks, which can be exploited to cause a DoS by tricking an application using the library into processing a specially crafted PNG file. The vulnerability is reported in versions prior to 1.0.53, 1.2.43, and 1.4.1. SOLUTION: Update to version 1.0.53, 1.2.43, and 1.4.1 and follow the vendor's instructions to increase protection against the so called "decompression bombs": http://libpng.sourceforge.net/decompression_bombs.html PROVIDED AND/OR DISCOVERED BY: Reported by the PNG Development Group after encountering a malformed image in the wild.
