Summary
Stack-based buffer overflow in the cbtls_verify function in FreeRADIUS 2.1.10 through 2.1.12, when using TLS-based EAP methods, allows remote attackers to cause a denial of service (server crash) and possibly execute arbitrary code via a long "not after" timestamp in a client certificate.

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.
