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: 4.4
SynopsisThe remote Ubuntu host is missing a security-related patch.
DescriptionKeegan Ryan discovered that NSS incorrectly handled ECDSA key generation. A local attacker could possibly use this issue to perform a cache-timing attack and recover private ECDSA keys. (CVE-2018-0495)
