CVE-2015-0237
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedRed Hat Enterprise Virtualization (RHEV) Manager before 3.5.1 ignores the permission to deny snapshot creation during live storage migration between domains, which allows remote authenticated users to cause a denial of service (prevent host start) by creating a long snapshot chain.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceRHEV Manager before 3.5.1 fails to enforce snapshot creation permissions during live storage migration between storage domains. An authenticated remote user can exploit this authorization bypass to create an arbitrarily long chain of snapshots, which consumes storage resources and can prevent host startup, resulting in denial of service.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Check RHEV Manager versionRun 'rpm -q rhevm' or check the installed package version using your package managerAffected if Version is 3.5.0 or earlier (vulnerable versions are <= 3.5.0)
-
Verify live storage migration configurationCheck if live storage migration (also known as live storage move) is enabled in the RHEV Manager configuration. This can be verified through the admin portal under storage domain settings or via the API query for storage domain attributesAffected if Live storage migration feature is enabled and the RHEV Manager version is 3.5.0 or earlier
-
Audit snapshot inventory for anomalous chainsQuery the RHEV Manager API or admin portal for all snapshots. Look for storage domains containing unusually long chains of child snapshots (snapshots with multiple parent references) that were created during live storage migration operationsAffected if Excessive snapshot chains exist on storage domains, especially snapshots created without corresponding explicit user permission records in the audit log
You are affected if RHEV Manager version is 3.5.0 or earlier AND live storage migration is in use, as the authorization bypass allows unauthorized snapshot creation during migration operations.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpgrade RHEV Manager to version 3.5.1 or later, which contains the fix to properly enforce snapshot creation permissions during live storage migration.
