Debian DLA-2228-2 : json-c regression update

high Nessus Plugin ID 136984

Language:

Synopsis

The remote Debian host is missing a security update.

Description

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.

Solution

Upgrade the affected packages.
