Summary

Red Hat Security Advisory: rhev-hypervisor6 security, bug fix, and enhancement update

Severity

Important

Notes

Topic: An updated rhev-hypervisor6 package that fixes one security issue, various bugs, and adds enhancements is now available. The Red Hat Security Response Team has rated this update as having important security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.

Details: The rhev-hypervisor6 package provides a Red Hat Enterprise Virtualization Hypervisor ISO disk image. The Red Hat Enterprise Virtualization Hypervisor is a dedicated Kernel-based Virtual Machine (KVM) hypervisor. It includes everything necessary to run and manage virtual machines: A subset of the Red Hat Enterprise Linux operating environment and the Red Hat Enterprise Virtualization Agent. Note: Red Hat Enterprise Virtualization Hypervisor is only available for the Intel 64 and AMD64 architectures with virtualization extensions. A flaw was found in the way Red Hat Enterprise Virtualization Hypervisor hosts were added to the Red Hat Enterprise Virtualization environment. The Python scripts needed to configure the host for Red Hat Enterprise Virtualization were downloaded in an insecure way, that is, without properly validating SSL certificates during HTTPS connections. An attacker on the local network could use this flaw to conduct a man-in-the-middle attack, potentially gaining root access to the host being added to the Red Hat Enterprise Virtualization environment. This update provides the VDSM part of the fix. The RHSA-2012:1506 Red Hat Enterprise Virtualization Manager update must also be installed to completely fix this issue. (CVE-2012-0861) The CVE-2012-0861 issue was discovered by Red Hat. This updated package provides updated components that include a fix for one security issue. This issue had no security impact on Red Hat Enterprise Virtualization Hypervisor itself, however. The security fix included in this update addresses the following CVE number: CVE-2012-0860 (VDSM issue) This updated Red Hat Enterprise Virtualization Hypervisor package also fixes the following bug: * This update adds Hypervisor support for use in Red Hat Enterprise Virtualization 3.1 compatible clusters. (BZ#846811) This update includes: * A fence-agents bug fix update (RHBA-2012:1439). https://rhn.redhat.com/errata/RHBA-2012-1439.html * An ovirt-node bug fix update (RHBA-2012:1500). https://rhn.redhat.com/errata/RHBA-2012-1500.html * A libvirt bug fix update (RHBA-2012:1501). https://rhn.redhat.com/errata/RHBA-2012-1501.html * A sanlock bug fix and enhancement update (RHBA-2012:1507). https://rhn.redhat.com/errata/RHBA-2012-1507.html * An important vdsm security and enhancement update (RHSA-2012:1508). https://rhn.redhat.com/errata/RHBA-2012-1508.html * A qemu-kvm-rhev bug fix update (RHBA-2012:1510). https://rhn.redhat.com/errata/RHBA-2012-1510.html Users of the Red Hat Enterprise Virtualization Hypervisor are advised to upgrade to this updated package, which includes these security updates, bug fixes and enhancements.

CVE-2012-0861

The vds_installer in Red Hat Enterprise Virtualization Manager (RHEV-M) before 3.1, when adding a host, uses the -k curl parameter when downloading deployUtil.py and vds_bootstrap.py, which prevents SSL certificates from being validated and allows remote attackers to execute arbitrary Python code via a man-in-the-middle attack.

How durations are calculated

Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.

Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
