ClamAV AntiVirus software versions 0.99.2 and prior contain a vulnerability that could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to improper input validation checking mechanisms of .tar (Tape Archive) files sent to an affected device. A successful exploit could cause a checksum buffer over-read condition when ClamAV scans the malicious .tar file, potentially allowing the attacker to cause a DoS condition on the affected device.

Security readout for executives and security teams

ClamAV 0.99.2 and earlier can crash or stop scanning when it processes a specially crafted .tar archive. This is a denial-of-service issue, not a documented data theft or code execution issue in the provided sources. Exposure is most likely where ClamAV 0.99.2 or earlier scans untrusted archives, such as mail gateways, upload pipelines, file shares, or web content filters. Treat as a scheduled remediation item for systems that scan untrusted files. Prioritize internet-facing mail, upload, and content-filtering services because scanner outages can disrupt security controls and business workflows. Mitigation focus: Inventory ClamAV deployments and identify versions 0.99.2 or earlier.; Apply relevant Ubuntu, Debian, or upstream ClamAV security updates.; Review the ClamAV 0.99.3 release guidance before relying on version assumptions..
