Debian Security Advisory

DLA-2228-2 json-c -- LTS security update

Date Reported:
31 May 2020
Affected Packages:
json-c
Vulnerable:
Yes
Security database references:
In the Debian bugtracking system: Bug 960326.
In Mitre's CVE dictionary: CVE-2020-12762.
More information:

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.
