The libpng package contains a library of functions for creating and manipulating PNG (Portable Network Graphics) image format files.
Several vulnerabilities have been reported in libpng's handling of various PNG image chunks. An attacker could potentially exploit this vulnerability to cause an application opening a specially crafted PNG image file to crash while manipulating the file. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2007-5269 to these issues.S
