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
The Antivirus component in Comodo Internet Security before 5.3.174622.1216 does not check whether X.509 certificates in signed executable files have been revoked, which has unknown impact and remote attack vectors.

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 confidence

The Comodo Internet Security antivirus component before version 5.3.174622.1216 fails to perform certificate revocation checks on X.509 certificates embedded in signed executable files. This allows potentially malicious code signed with revoked or compromised certificates to bypass the antivirus security validation, as the system does not verify whether the signing certificate has been revoked via CRL or OCSP.

MitigationUpgrade Comodo Internet Security to version 5.3.174622.1216 or later, which implements proper X.509 certificate revocation checking for signed executables. Until upgraded, exercise extreme caution with any signed executable, even from seemingly trusted sources.

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 Comodo Internet Security is installed
    Look for Comodo Internet Security in the list of installed programs via Control Panel > Programs and Features, or check for Comodo antivirus processes running in Task Manager.
    Affected if Comodo Internet Security is present on the system
  2. Locate the installed version number
    Open Comodo Internet Security, navigate to Help > About, or right-click the COMODO icon in the system tray and select About. The version is typically displayed in the format X.X.XXXXXX.XXXX.
    Affected if Unable to retrieve version information from the Comodo installation
  3. Compare the version against the affected ranges
    Compare your installed version number to the following affected versions: any version <= 5.0.163652.1142, or specifically versions 3.0.14.276, 3.0.15.277, 3.0.16.295, 3.0.17.304, 3.0.18.309, 3.0.19.318, 3.0.20.320, 3.0.22.349, 3.0.23.364, 3.0.24.368, or 3.0.25.378.
    Affected if Your installed version matches or falls within these affected version ranges

If Comodo Internet Security is installed and the version is either <= 5.0.163652.1142 or matches one of the listed 3.0.x versions, the certificate revocation checking vulnerability is present in your environment.
