Scientific Linux Security Update : nss and nspr on SL7.x x86_64 (20201001)

Critical Nessus Plugin ID 141689

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: 5.9


The remote Scientific Linux host is missing one or more security updates.
