Debian DLA-471-1 : jansson security update

high Nessus Plugin ID 91133

Language:

Synopsis

The remote Debian host is missing a security update.

Description

Applications that depend on Jansson, a C library for encoding, decoding and manipulating JSON data, could crash due to stack exhaustion while parsing a JSON file. This was caused due to an unlimited parsing depth when parsing JSON arrays and is now fixed by limiting the depth to 2048.

For Debian 7 'Wheezy', this problem has been fixed in version 2.3.1-2+deb7u1.

We recommend that you upgrade your jansson 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.
