"Several issues have been found for gpac, an Open Source multimedia
framework. Using crafted files one can trigger buffer overflow issues
that could be used to crash the application.

For Debian 8 'Jessie', these problems have been fixed in version
0.5.0+svn5324~dfsg1-1+deb8u3.

We recommend that you upgrade your gpac 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."
