"It was found that an out of bounds write caused by a heap-based buffer
overflow could be triggered in freetype via a crafted font.

This update also reverts the fix for CVE-2016-10328, as it was
determined that freetype 2.4.9 is not affected by that issue.

For Debian 7 'Wheezy', these problems have been fixed in version
2.4.9-1.1+deb7u6.

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."
