Detailed vulnerability description
The vulnerability allows remote attackers to perform a denial of service (DoS) attack.

A remote attacker can cause a denial of service (application crash) via a crafted PNG image that triggers an out-of-bounds read during the copying of error-message data. NOTE: this vulnerability exists because of a CVE-2004-0421 regression.
