Description Vasyl Kaigorodov 2015-02-10 07:50:27 EST 
Common Vulnerabilities and Exposures assigned CVE-2014-9659 to the following issue:

cff/cf2intrp.c in the CFF CharString interpreter in FreeType before 2.5.4
proceeds with additional hints after the hint mask has been computed, which
allows remote attackers to execute arbitrary code or cause a denial of service
(stack-based buffer overflow) via a crafted OpenType font.  NOTE: this
vulnerability exists because of an incomplete fix for CVE-2014-2240.
