The ENSURE_BITS macro in mszipd.c for Clam AntiVirus (ClamAV) 0.83, and other versions vefore 0.86, allows remote attackers to cause a denial of service (CPU consumption by infinite loop) via a cabinet (CAB) file with the cffile_FolderOffset field set to 0xff, which causes a zero-length read.

Security readout for executives and security teams

A malformed Microsoft Cabinet file could make older ClamAV scanners consume CPU indefinitely. The business impact is denial of service: mail, file upload, or gateway scanning could stall on affected legacy deployments. The source bundle does not provide CVSS or evidence of active exploitation. Exposure is most likely in obsolete systems still running ClamAV 0.83 or other versions before 0.86, especially where untrusted CAB files are scanned through email, upload, or file gateway workflows. Treat this as a legacy hygiene issue unless affected scanners remain in production. If legacy ClamAV handles untrusted files, remediation should be prioritized because availability of scanning services can be directly affected. Mitigation focus: Inventory ClamAV deployments and identify versions before 0.86.; Upgrade ClamAV to 0.86 or vendor-fixed packages where applicable.; Review Debian DSA-737 or current vendor guidance for package-specific fixes..
