Summary
Multiple buffer underflows in the base64 decoder in base64.c in (1) bogofilter and (2) bogolexer in bogofilter before 1.2.2 allow remote attackers to cause a denial of service (heap memory corruption and application crash) via an e-mail message with invalid base64 data that begins with an = (equals) character.

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.
