Description Vasyl Kaigorodov 2015-02-10 07:52:04 EST

Common Vulnerabilities and Exposures assigned CVE-2014-9668 to the following issue:

The woff_open_font function in sfnt/sfobjs.c in FreeType before 2.5.4 proceeds
with offset+length calculations without restricting length values, which allows
remote attackers to cause a denial of service (integer overflow and heap-based
buffer overflow) or possibly have unspecified other impact via a crafted Web
Open Font Format (WOFF) file.
