Originalnachricht |
Name : jansson Product : Fedora 20 Version : 2.6 Release : 1.fc20 URL : http://www.digip.org/jansson/ Summary : C library for encoding, decoding and manipulating JSON data Description : Small library for parsing and writing JSON documents.
------------------------------------------------------------------------------- - Update Information:
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)
