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 AIX host is missing a security patch.
DescriptionThe remote AIX host has a version of Network Time Protocol (NTP) installed that is affected by a denial of service vulnerability due to a flaw in the symmetric-key feature in the receive() function in file ntp_proto.c when receiving certain invalid packets, which causes state-variable updates to be performed. A man-in-the-middle attacker can exploit this, by spoofing the source IP of a peer, to cause a synchronization loss.
SolutionInstall the appropriate interim fix according to the vendor advisory.
