"The json-c shared library had an integer overflow and out-of-bounds
write via a large JSON file, as demonstrated by printbuf_memappend.

This follow-up version now uses an upstream sanctioned patch that was
specifically published for json-c 0.11, rather than a self-backported
patch.

For Debian 8 'Jessie', this problem has been fixed in version
0.11-4+deb8u2.

We recommend that you upgrade your json-c 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.");
