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: 3.4
SynopsisThe remote Scientific Linux host is missing a security update.
DescriptionA flaw was discovered in the way the ntpd daemon checked the return value of the OpenSSL EVP_VerifyFinal function. On systems using NTPv4 authentication, this could lead to an incorrect verification of cryptographic signatures, allowing time-spoofing attacks.
Note: This issue only affects systems that have enabled NTP authentication. By default, NTP authentication is not enabled.
After installing the update, the ntpd daemon will restart automatically.
SolutionUpdate the affected ntp package.
