Description Vasyl Kaigorodov 2015-02-10 12:50:57 UTC

Common Vulnerabilities and Exposures assigned CVE-2014-9662 to the following issue:

cff/cf2ft.c in FreeType before 2.5.4 does not validate the return values of
point-allocation functions, which allows remote attackers to cause a denial of
service (heap-based buffer overflow) or possibly have unspecified other impact
via a crafted OTF font.

Upstream bug is:
https://savannah.nongnu.org/bugs/?43658

Issue was fixed upstream in 2.5.4.

The CFF parsing code affected by this issue was only 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, which are based on earlier upstream versions.

Statement:

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