Synopsis

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

Description

The remote Redhat Enterprise Linux 8 host has a package installed that is affected by multiple vulnerabilities as referenced in the RHSA-2022:6551 advisory.

- kernel: Small table perturb size in the TCP source port generation algorithm can lead to information leak (CVE-2022-1012)

- dpdk: DoS when a Vhost header crosses more than two descriptors and exhausts all mbufs (CVE-2022-2132)

- systemd-resolved: use-after-free when dealing with DnsStream in resolved-dns-stream.c (CVE-2022-2526)

- kernel: a use-after-free in cls_route filter implementation may lead to privilege escalation (CVE-2022-2588)

- rsync: remote arbitrary files write inside the directories of connecting peers (CVE-2022-29154)

- kernel: a use-after-free write in the netfilter subsystem can lead to privilege escalation to root (CVE-2022-32250)

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

Solution

Update the RHEL Red Hat Virtualization package based on the guidance in RHSA-2022:6551.
