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

high Nessus Plugin ID 136984
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


The remote Debian host is missing a security update.


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.


Upgrade the affected packages.
