"Florian Weimer of the Red Hat Product Security Team found that the
hashing implementation in Jansson, a library for encoding, decoding
and manipulating JSON data, was susceptible to predictable hash
collisions.

A remote attacker could use this flaw to cause an application using
Jansson to use an excessive amount of CPU time by sending a crafted
JSON document containing a large number of parameters whose names map
to the same hash value. (CVE-2013-6401)

Note that Tenable Network Security has extracted the preceding
description block directly from the Fedora security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
