Summary
Red Hat Security Advisory: Red Hat Virtualization Host 4.4.z SP 1 security update batch#5 (oVirt-4.5.3-5)

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. The ovirt-node-ng 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): * git: gitattributes parsing integer overflow (CVE-2022-23521) * git: Heap overflow in `git archive`, `git log --format` leading to RCE (CVE-2022-41903) * ALSA: pcm: Move rwsem lock inside snd_ctl_elem_read to prevent UAF (CVE-2023-0266) * kernel: FUSE filesystem low-privileged user privileges escalation (CVE-2023-0386) * nss: Arbitrary memory write via PKCS 12 (CVE-2023-0767) 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.

When parsing gitattributes, a mechanism to allow defining attributes for paths, multiple integer overflows can occur when there is a huge number of path patterns, attributes for a single pattern, or declared attribute names. These overflows can be triggered via a crafted `.gitattributes` file that may be part of the commit history. Git silently splits lines longer than 2KB when parsing gitattributes from a file, but not when parsing them from the index. Consequentially, the failure mode depends on whether the file exists in the working tree, the index, or both. This integer overflow can result in arbitrary heap reads and writes, which may allow remote code execution.",
