Summary

Red Hat Security Advisory: virtio-win security and bug fix update

Severity

Important

Notes

Topic: An updated virtio-win package that fixes one security issue and two bugs is now available for Red Hat Enterprise Linux 6 Supplementary. Red Hat Product Security 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 virtio-win package provides paravirtualized network drivers for most Microsoft Windows operating systems. Paravirtualized drivers are virtualization-aware drivers used by fully virtualized guests running on Red Hat Enterprise Linux. Fully virtualized guests using the paravirtualized drivers gain significantly better I/O performance than fully virtualized guests running without the drivers. It was found that the Windows Virtio NIC driver did not sufficiently sanitize the length of the incoming IP packets, as demonstrated by a packet with IP options present but the overall packet length not being adjusted to reflect the length of those options. A remote attacker able to send a specially crafted IP packet to the guest could use this flaw to crash that guest. (CVE-2015-3215) Red Hat would like to thank Google Project Zero for reporting this issue. This update also fixes the following bugs: * When creating a Windows guest using virtio drivers and direct Logical Unit Number (LUN) access with more than 4 SCSI disks under one virtio-scsi-pci controller, the guest terminated unexpectedly with a stop error, also known as the blue screen of death. This update increases the maximum amount of LUNs per a single virtio-scsi-pci controller has been increased to 254, which prevents the described crash from occurring. (BZ#1210196) * The license.txt file in the virtio-win build has been updated to include the correct year number in the copyright information section. (BZ#1210195) All virtio-win users are advised to upgrade to this updated package, which contains backported patches to correct these issues.

Vulnerability from cvelistv5 – Published: 2017-06-26 15:00 – Updated: 2024-08-06 05:39

Summary

The NetKVM Windows Virtio driver allows remote attackers to cause a denial of service (guest crash) via a crafted length value in an IP packet, as demonstrated by a value that does not account for the size of the IP options.

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.

Related by attack behaviour

Vulnerabilities whose description is nearest to this one in the vector space of the CIRCL/vulnerability-attack-technique-biencoder model. This is a similarity search over the bi-encoder space (plain cosine), not a classification, and it has no measured accuracy.
