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 or potentially execute arbitrary code on an affected device. The vulnerability is due to improper input validation checking mechanisms in mew packet files sent to an affected device. A successful exploit could cause a heap-based buffer over-read condition in mew.c when ClamAV scans the malicious file, allowing the attacker to cause a DoS condition or potentially execute arbitrary code on the affected device.

Security readout for executives and security teams

ClamAV 0.99.2 and earlier can mishandle specially crafted MEW-packed files during scanning. An unauthenticated remote attacker could trigger a crash and possibly arbitrary code execution when the file is processed. This matters most where ClamAV scans email, uploads, gateways, or shared files from untrusted sources. Exposure is likely on systems running ClamAV AntiVirus 0.99.2 or prior, especially mail gateways, file-upload scanners, web gateways, and automated scanning pipelines that process untrusted files. Treat this as a high-priority hygiene fix for any internet-facing or mail-processing environment still using old ClamAV. The vulnerability is old, but affected software is also old, so remaining exposure suggests patch-management gaps. Mitigation focus: Upgrade ClamAV using vendor security guidance for this CVE.; Prioritize Ubuntu and Debian package security updates where those distributions are used.; Review the ClamAV 0.99.3 release advisory before choosing an upstream version..
