Updated freetype packages has been released for Debian 7 LTS

Package : freetype
Version : 2.4.9-1.1+deb7u4
CVE ID : CVE-2016-10244
Debian Bug : #856971

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 "Wheezy", this issue has been fixed in freetype version
2.4.9-1.1+deb7u4.

We recommend that you upgrade your freetype packages.
