"Three issues have been found for gpac, an Open Source multimedia
framework. Two of them are NULL pointer dereferences and one of them
is a heap-based buffer overflow.

For Debian 8 'Jessie', these problems have been fixed in version
0.5.0+svn5324~dfsg1-1+deb8u4.

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."
