Debian DSA-3577-1 : jansson - security update

high Nessus Plugin ID 91139

Language:

Synopsis

The remote Debian host is missing a security-related update.

Description

Gustavo Grieco discovered that jansson, a C library for encoding, decoding and manipulating JSON data, did not limit the recursion depth when parsing JSON arrays and objects. This could allow remote attackers to cause a denial of service (crash) via stack exhaustion, using crafted JSON data.

Solution

Upgrade the jansson packages.

For the stable distribution (jessie), this problem has been fixed in version 2.7-1+deb8u1.
