libpng contains a flaw in the decompression of PNG files that may allow a remote denial of service. The issue is triggered when the 'png_decompress_chunk()' function in pngrutil.c fails to properly decompress certain highly compressed ancillary-chunk data. With a specially crafted PNG file, a context-dependent attacker can cause the system to exhaust the CPU and memory.
