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).");
