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 when handling Portable Document Format (.pdf) files sent to an affected device. An unauthenticated, remote attacker could exploit this vulnerability by sending a crafted .pdf file to an affected device. This action could cause a handle_pdfname (in pdf.c) buffer overflow when ClamAV scans the malicious file, allowing the attacker to cause a DoS condition or potentially execute arbitrary code.

Security readout for executives and security teams

Older ClamAV versions can crash, and may run attacker-controlled code, when they scan a specially crafted PDF. This matters because ClamAV is often placed where untrusted files arrive first, such as mail or upload scanning. The source bundle does not show active exploitation. Exposure is limited to ClamAV AntiVirus 0.99.2 and prior. Risk is highest where ClamAV scans untrusted PDF files from email, uploads, shared storage, or automated ingestion pipelines. Prioritize remediation where ClamAV scans files from external users or partners. Even without confirmed active exploitation, unauthenticated DoS and possible code execution in a security scanning component create meaningful operational risk. Mitigation focus: Upgrade ClamAV beyond 0.99.2 using vendor-supported packages.; Apply referenced Ubuntu or Debian ClamAV security updates where applicable.; Review ClamAV 0.99.3 release guidance for fixed upstream behavior..
