## 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.
