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: 8.4

Synopsis

The remote Red Hat host is missing one or more security updates.

Description

The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2020:5199 advisory.

- kernel: metadata validator in XFS may cause an inode with a valid, user-creatable extended attribute to be flagged as corrupt (CVE-2020-14385)

- kernel: memory corruption in net/packet/af_packet.c leads to elevation of privilege (CVE-2020-14386)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution
