Debian DLA-2301-1 : json-c security update

Medium Nessus Plugin ID 139209

Synopsis

The remote Debian host is missing a security update.

Description

Tobias Stoeckmann found an integer overflow issue in JSON-C, a C library to manipulate JSON objects, when reading maliciously crafted large files. The issue could be exploited to cause denial of service or possibly execute arbitrary code.

For Debian 9 stretch, this problem has been fixed in version 0.12.1-1.1+deb9u1.

We recommend that you upgrade your json-c packages.

For the detailed security status of json-c please refer to its security tracker page at:
https://security-tracker.debian.org/tracker/json-c

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.
