Security Advisory Important

Topic

An update for redhat-release-virtualization-host and redhat-virtualization-host is now available for Red Hat Virtualization 4 for Red Hat Enterprise Linux 8.

Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

Description

The redhat-virtualization-host packages provide the Red Hat Virtualization Host. These packages include redhat-release-virtualization-host, ovirt-node, and rhev-hypervisor. Red Hat Virtualization Hosts (RHVH) are installed using a special build of Red Hat Enterprise Linux with only the packages required to host virtual machines. RHVH features a Cockpit user interface for monitoring the host's resources and performing administrative tasks.

Security Fix(es):

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

  • 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: 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)
