Summary
clamav vulnerabilities
Details
Michał Dardas discovered that ClamAV incorrectly handled parsing CHM files. A remote attacker could possibly use this issue to cause ClamAV to stop responding, resulting in a denial of service. (CVE-2022-20770)
Michał Dardas discovered that ClamAV incorrectly handled parsing TIFF files. A remote attacker could possibly use this issue to cause ClamAV to stop responding, resulting in a denial of service. (CVE-2022-20771)
Michał Dardas discovered that ClamAV incorrectly handled parsing HTML files. A remote attacker could possibly use this issue to cause ClamAV to consume resources, resulting in a denial of service. (CVE-2022-20785)
Michał Dardas discovered that ClamAV incorrectly handled loading the signature database. A remote attacker could possibly use this issue to cause ClamAV to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2022-20792)
Alexander Patrakov and Antoine Gatineau discovered that ClamAV incorrectly handled the scan verdict cache check. A remote attacker could possibly use this issue to cause ClamAV to crash, resulting in a denial of service, or possibly execute arbitrary code.(CVE-2022-20796)

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
