Title: LibPNG Wide Image Processing Memory Corruption Vulnerability
Severity: HIGH
Description:
The libpng graphics library is reported to be prone to a security-related issue with regards to handling of overly wide images. It may be possible to corrupt memory with an overly wide PNG image. An attacker may be able to exploit this condition to execute arbitrary code with the privileges of an application or client which handles the overly wide image, though this possibility has not been confirmed.
It may be possible to exploit this issue via a web client that is configured to load PNG images automatically.
Patches have been released which address this condition by preventing libpng from processing overly wide images.
