Xavier Roche discovered that libgd2 did not correctly validate PNG
callback results. If an application were tricked into processing a
specially crafted PNG image, it would monopolize CPU resources. Since
libgd2 is often used in PHP and Perl web applications, this could lead
to a remote denial of service. (CVE-2007-2756)");
