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: 5.2
SynopsisThe remote Mandriva Linux host is missing one or more security updates.
DescriptionMultiple vulnerabilities has been found and corrected in ntp :
The symmetric-key feature in the receive function in ntp_proto.c in ntpd in NTP before 4.2.8p2 requires a correct MAC only if the MAC field has a nonzero length, which makes it easier for man-in-the-middle attackers to spoof packets by omitting the MAC (CVE-2015-1798).
The symmetric-key feature in the receive function in ntp_proto.c in ntpd in NTP before 4.2.8p2 performs state-variable updates upon receiving certain invalid packets, which makes it easier for man-in-the-middle attackers to cause a denial of service (synchronization loss) by spoofing the source IP address of a peer (CVE-2015-1799).
The updated packages provides a solution for these security issues.
SolutionUpdate the affected ntp, ntp-client and / or ntp-doc packages.
