New! Vulnerability Priority Rating (VPR)
Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.
VPR Score: 3.6
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).
Solution
Update the affected lib64json-devel and / or lib64json2 packages.
