Mandriva Linux Security Advisory MDVSA-2015:102
http://www.mandriva.com/en/support/security/
_______________________________________________________________________

Package : json-c
Date : March 29, 2015
Affected: Business Server 2.0
_______________________________________________________________________

Problem 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).
