Security readout for executives and security teams
Plain-English summary
This CVE describes a denial-of-service condition in VDSM for Red Hat Enterprise Virtualization 3 and 3.2. A privileged user inside a guest VM could make the host appear unavailable to the management server by sending unexpected guest information fields.
Executive priority
Prioritize if legacy RHEV 3.x hosts are still operating important workloads, especially in shared environments. It is not evidenced as actively exploited, but host management disruption can affect operations and incident response.
Technical view
The issue is in VDSM handling of guestInfo dictionaries containing unexpected fields. The documented impact is host management unavailability, not data theft or code execution. The source bundle provides no CVSS score, CWE, detailed affected package list, or confirmed exploit activity.
Likely exposure
Exposure appears limited to legacy Red Hat Enterprise Virtualization 3 and 3.2 deployments using VDSM, especially where privileged guest users exist. Organizations not running these legacy virtualization platforms are unlikely to be exposed based on the provided sources.
Exploitation context
No provided source states active exploitation, and the CVE is not flagged in KEV. The described attacker already needs privileged access inside a guest VM, making this more relevant to tenant isolation and operational resilience than internet perimeter exposure.
Researcher notes
The public record is sparse. The reliable details are product family, affected major versions, privileged guest precondition, malformed guestInfo fields, and host management unavailability. Do not assume broader Red Hat products, remote unauthenticated exposure, or specific fixes beyond the cited advisories.
Mitigation direction
- Review Red Hat advisories RHSA-2013:0907 and RHSA-2013:0886 for applicable updates.
- Apply vendor-supported VDSM or Red Hat Enterprise Virtualization fixes where systems remain in service.
- Restrict privileged guest access to trusted administrators and workloads.
- Monitor virtualization management availability and host disconnect events.
- Plan retirement or isolation for unsupported RHEV 3.x environments.
Validation and detection
- Inventory Red Hat Enterprise Virtualization 3 and 3.2 environments.
- Identify installed VDSM versions and compare them with Red Hat advisory guidance.
- Confirm whether vendor errata RHSA-2013:0907 or RHSA-2013:0886 were applied.
- Review management server logs for hosts becoming unexpectedly unavailable.
- Check whether privileged guest users exist in shared or multi-tenant environments.
