Security readout for executives and security teams
This flaw affects the Antivirus component of Comodo Internet Security versions before 3.11.108364.552. A malicious compressed file could cause excessive memory use, leading to denial of service. The sources do not report data theft, code execution, or active exploitation. Exposure is likely limited to systems still running Comodo Internet Security Antivirus before 3.11.108364.552. The bundled affected-product metadata is incomplete, so confirm exposure by local software inventory rather than CPE matching alone. Treat as a legacy availability risk. It is not reported as actively exploited, but vulnerable antivirus software can create operational disruption when handling malicious archives. Address during endpoint hygiene and unsupported software cleanup. Mitigation focus: Identify any Comodo Internet Security installations and versions.; Upgrade versions before 3.11.108364.552 per vendor release guidance.; Check current vendor guidance for supported replacement versions..
