Summary
libheif vulnerabilities
Details
It was discovered that libheif had an integer underflow in the Fraction constructor when a clap transform was applied twice. An attacker could possibly use this issue to cause libheif to crash, resulting in a denial of service. (CVE-2026-62289)
It was discovered that libheif had an out-of-bounds read in uncompressed tile range slicing. An attacker could possibly use this issue to cause libheif to crash, resulting in a denial of service. This issue only affected Ubuntu 25.10. (CVE-2026-62292)

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.
