Summary

Red Hat Security Advisory: Red Hat Virtualization Host security and bug fix update [ovirt-4.4.10] Async #1

Notes

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.

Details

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) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

Vulnerability from cvelistv5

Published

Severity ?

Summary

A use-after-free flaw was found in cgroup1_parse_param in kernel/cgroup/cgroup-v1.c in the Linux kernel's cgroup v1 parser. A local attacker with a user privilege could cause a privilege escalation by exploiting the fsconfig syscall parameter leading to a container breakout and a denial of service on the system.

Vulnerability from cvelistv5

Summary

A flaw was found in the way the "flags" member of the new pipe buffer structure was lacking proper initialization in copy_page_to_iter_pipe and push_pipe functions in the Linux kernel and could thus contain stale values. An unprivileged local user could use this flaw to write to pages in the page cache backed by read only files and as such escalate their privileges on the system.
