Debian Security Advisory DSA-3577-1 [email protected]
https://www.debian.org/security/ Alessandro Ghedini
May 14, 2016 https://www.debian.org/security/faq

Package : jansson
CVE ID : CVE-2016-4425
Debian Bug : 823238

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.

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

For the unstable distribution (sid), this problem has been fixed in
version 2.7-5.

We recommend that you upgrade your jansson packages.
