Summary

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

Severity

Important

Notes

Topic: An updated rhev-hypervisor6 package that fixes one security issue and one bug 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 socket buffers (skb) requiring TSO (TCP segment offloading) were handled by the sfc driver. If the skb did not fit within the minimum-size of the transmission queue, the network card could repeatedly reset itself. A remote attacker could use this flaw to cause a denial of service. (CVE-2012-3412) Red Hat would like to thank Ben Hutchings of Solarflare (tm) for reporting this issue. 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-2012-4423 (libvirt issue) This update also fixes the following bug: * A dependency issue was found between the rhev-hypervisor-tools and rhev-hypervisor6-tools packages. Every time a user with one of the -tools packages installed ran "yum update", the -tools package they had installed was removed and the other one installed. Even though rhev-hypervisor-tools obsoleted rhev-hypervisor6-tools, this update includes an updated rhev-hypervisor6-tools package that corrects this issue. Note that the package does not have meaningful content, is only here to fix the dependency issue, and may be removed by a future update. (BZ#855391) This update includes the ovirt-node build from RHBA-2012:1374: https://rhn.redhat.com/errata/RHBA-2012-1374.html Users of the Red Hat Enterprise Virtualization Hypervisor are advised to upgrade to this updated package, which fixes these issues.

CVE-2012-3412

The sfc (aka Solarflare Solarstorm) driver in the Linux kernel before 3.2.30 allows remote attackers to cause a denial of service (DMA descriptor consumption and network-controller outage) via crafted TCP packets that trigger a small MSS value.

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.
