Libpng Library Unknown Chunk Handler Vulnerability

The 'libpng' library is prone to a vulnerability that causes denial-of-service conditions or may allow code to run. The issue occurs because the software fails to properly handle unexpected chunk data in PNG files.

Successfully exploiting this issue allows remote attackers to trigger denial-of-service conditions or to possibly execute arbitrary machine code in the context of applications that use the library.

The following versions are affected:

libpng 1.0.6 through 1.0.32
libpng 1.2.0 through 1.2.26
libpng 1.4.0beta01 through 1.4.0beta19
