Summary

The StripTags function in (1) the USF decoder (modules/codec/subtitles/subsdec.c) and (2) the Text decoder (modules/codec/subtitles/subsusf.c) in VideoLAN VLC Media Player 1.1 before 1.1.6-rc allows remote attackers to execute arbitrary code via a subtitle with an opening "<" without a closing ">" in an MKV file, which triggers heap memory corruption, as demonstrated using refined-australia-blu720p-sample.mkv.

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.
