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 'Wheezy', 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."
