Vulnerability Description
A vulnerability was reported in Mozilla Firefox. Firefox is a popular, open source web browser developed by Mozilla Foundation. Mozilla Firefox fails to properly process animated Portable Network Graphics (APNG) image files. A remote attacker could exploit this vulnerability by persuading a target user to open a specially crafted PNG image. Successful exploitation could lead to arbitrary code execution or terminate the application, resulting in a Denial of Service condition.
Vulnerability Details
The flaw is due to integer overflow when processing animated PNG (APNG) files. APNG is an extension of PNG developed by Mozilla Foundation that supports animated images.
