USN-1-1: PNG library vulnerabilities
First published: Sat Oct 23 2004(Updated: )
Several integer overflow vulnerabilities were discovered in the PNG library. These vulnerabilities could be exploited by an attacker by providing a specially crafted PNG image which, when processed by the PNG library, could result in the execution of program code provided by the attacker. The PNG library is used by a variety of software packages for different purposes, so the exact nature of the exposure will vary depending on the software involved.
