Description Vasyl Kaigorodov 2015-02-10 12:50:27 UTC
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.

Upstream bug is:

Issue was fixed upstream in 2.5.4.

Report indicates this is issue is an incomplete fix / variant of the CVE-2014-2240 issue (bug 1074646).  It affects code which was introduced in upstream version 2.4.12, and enabled by default in 2.5.  The affected code is not in freetype packages in Red Hat Enterprise Linux 7 and earlier.


Not vulnerable. This issue did not affect the versions of freetype as shipped with Red Hat Enterprise Linux 5, 6 and 7.
