libgd2: buffer overflows in PNG handling
| Package(s): | libgd2 | CVE #(s): | CAN-2004-0990 CAN-2004-0941 | |||||||||||||||||||||||||||||||||||||||||||||||||||
| Created: | October 29, 2004 | Updated: | June 28, 2006 | |||||||||||||||||||||||||||||||||||||||||||||||||||
| Description: | Several buffer overflows have been discovered in libgd's PNG handling
functions.
If an attacker tricked a user into loading a malicious PNG image, they could leverage this into executing arbitrary code in the context of the user opening image. Most importantly, this library is commonly used in PHP. One possible target would be a PHP driven photo website that lets users upload images. Therefore this vulnerability might lead to privilege escalation to a web server's privileges. Multiple buffer overflows in the gd graphics library (libgd) 2.0.21 and earlier may allow remote attackers to execute arbitrary code via malformed image files that trigger the overflows due to improper calls to the gdMalloc function. | |||||||||||||||||||||||||||||||||||||||||||||||||||||
