Who is Vulnerable?
Vulnerability Description	Web Open Fonts Format (WOFF) is a compressed version of sfnt-based fonts (Apple TrueType, Microsoft OpenType and Open FontFormat fonts). Mozilla Foundation included support to the WOFF format starting from Firefox 3.6. The new font format files use the extension ".woff". A remote code execution vulnerability has been reported in Mozilla Firefox. The vulnerability is due to an integer overflow error in a font decompression routine within the Web Open Fonts Format (WOFF) decoder. This issue may be exploited by remote attackers to execute arbitrary code on the target machine by enticing a user to open a maliciously crafted WOFF file. Successful exploitation of this vulnerability will crash the browser, and may allow execution of arbitrary code on the vulnerable system.
