RHEL 8 : Red Hat Virtualization Host security and bug fix update [ovirt-4.4.10] Async #1 (Important) (RHSA-2022:0841)

high Nessus Plugin ID 158924

Synopsis

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

Description

The remote Redhat Enterprise Linux 8 host has a package installed that is affected by multiple vulnerabilities as referenced in the RHSA-2022:0841 advisory.

- kernel: Use After Free in unix_gc() which could result in a local privilege escalation (CVE-2021-0920)

- kernel: local privilege escalation by exploiting the fsconfig syscall parameter leads to container breakout (CVE-2021-4154)

- kernel: possible privileges escalation due to missing TLB flush (CVE-2022-0330)

- kernel: remote stack overflow via kernel panic on systems using TIPC may lead to DoS (CVE-2022-0435)

- kernel: improper initialization of the flags member of the new pipe_buffer (CVE-2022-0847)

- kernel: failing usercopy allows for use-after-free exploitation (CVE-2022-22942)

- cyrus-sasl: failure to properly escape SQL input allows an attacker to execute arbitrary SQL commands (CVE-2022-24407)

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 affected redhat-virtualization-host-image-update package.
