Vulnerability from osv_ubuntu – Published: 2026-10-26 22:16 – Updated: 2026-10-28 17:50 – Source website

Details

Libpff through 20260926 contains a heap out-of-bounds read vulnerability in libpff_table_read_values_array because a 7c column definition's values_array_size is not checked against remaining buffer bytes. Attackers can supply a crafted PST, OST or PAB file to make applications read adjacent heap memory into record entry values or crash.

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.
Browse all ATT&CK techniques and the vulnerabilities related to each.
