Description Vasyl Kaigorodov 2015-02-10 12:50:07 UTC
Common Vulnerabilities and Exposures assigned CVE-2014-9657 to the following issue:

The tt_face_load_hdmx function in truetype/ttpload.c in FreeType before 2.5.4
does not establish a minimum record size, which allows remote attackers to cause
a denial of service (out-of-bounds read) or possibly have unspecified other
impact via a crafted TrueType font.
