RHSA-2014:0703-01 -- Redhat json-c

JSON-C implements a reference counting object model that allows you to easily construct JSON objects in C, output them as JSON-formatted strings, and parse JSON-formatted strings back into the C representation of JSON objects. Multiple buffer overflow flaws were found in the way the json-c library handled long strings in JSON documents. An attacker able to make an application using json-c parse excessively large JSON input could cause the application to crash. A denial of service flaw was found in the implementation of hash arrays in json-c. An attacker could use this flaw to make an application using json-c consume an excessive amount of CPU time by providing a specially crafted JSON document that triggers multiple hash function collisions. To mitigate this issue, json-c now uses a different hash function and randomization to reduce the chance of an attacker successfully causing intentional collisions. These issues were discovered by Florian Weimer of the Red Hat Product Security Team. All json-c users are advised to upgrade to these updated packages, which contain backported patches to correct these issues.
