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 · unedited
VDSM allows remote attackers to cause a denial of service (connection blocking) by keeping an SSL connection open.

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 · moderate confidence

VDSM (Virtual Desktop Server Manager) contains a denial of service vulnerability where remote attackers can block legitimate connections by keeping SSL connections open indefinitely, preventing new connections from being established.

MitigationImplement connection timeouts and connection limits on SSL endpoints to prevent attackers from exhausting available connections by holding them open.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Confirm VDSM installation
    Identify whether Virtual Desktop Server Manager (VDSM) or Red Hat Virtual Desktop Service Manager is present on the system
    Affected if VDSM is installed and running with SSL connectivity enabled
  2. Verify SSL endpoint exposure
    Determine if VDSM is configured to accept SSL connections on any network interface or port
    Affected if SSL endpoints are open and accessible from the network
  3. Inspect connection timeout configuration
    Examine the SSL configuration files or settings to determine whether connection timeouts are defined for VDSM connections
    Affected if No connection timeouts are configured or timeouts are set to unlimited
  4. Check connection limit settings
    Review SSL endpoint configuration to see if maximum connection limits or throttling are enforced
    Affected if No connection limits are configured, allowing unlimited concurrent SSL connections

A system is affected if VDSM is running with SSL endpoints that lack both connection timeouts and connection limits, allowing an attacker to exhaust available connections by holding them open indefinitely
