Name of the Vulnerable Software and Affected Versions SWFTools version 2013-04-09-1007

Description The issue arises from the mishandling of a malformed TTF file by the font2swf component, leading to a potential Denial of Service (DoS) due to an Access Violation. This can be triggered when font2swf processes a specially crafted TTF file, causing the program to crash.
