Mandriva Linux Security Advisory : json-c (MDVSA-2014:079)

This script is Copyright (C) 2014 Tenable Network Security, Inc.


Synopsis :

The remote Mandriva Linux host is missing one or more security
updates.

Description :

Updated json-c packages fix security vulnerabilities :

Florian Weimer reported that the printbuf APIs used in the json-c
library used ints for counting buffer lengths, which is inappropriate
for 32bit architectures. These functions need to be changed to using
size_t if possible for sizes, or to be hardened against negative
values if not. This could be used to cause a denial of service in an
application linked to the json-c library (CVE-2013-6370).

Florian Weimer reported that the hash function in the json-c library
was weak, and that parsing smallish JSON strings showed quadratic
timing behaviour. This could cause an application linked to the json-c
library, and that processes some specially crafted JSON data, to use
excessive amounts of CPU (CVE-2013-6371).
