Summary
Details
libjpeg-turbo 3.2.0 contains an integer division-by-zero vulnerability in the PNG loader. When processing a valid indexed-color PNG image with a non-gray palette through tj3LoadImage12() or tj3LoadImage16() using the default pixel format, the application may trigger a division-by-zero in alloc_sarray(), causing a SIGFPE and denial of service.
Severity
6.5 (Medium)

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.
