It was discovered that there was a denial of service vulnerability in freetype, a font rendering library.
The parse_charstrings function did not ensure that a font contains a glyph name, which allowed remote attackers to cause a denial of service via a specially crafted file.
For Debian 7 βWheezyβ, this issue has been fixed in freetype version 2.4.9-1.1+deb7u4.
We recommend that you upgrade your freetype packages.
NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
