OESA-2026-2982 (CVE-2026-50593)

Vulnerability from osv_openeuler – Published: 2026-07-19 11:11 – Updated: 2026-08-06 11:11 – Source website

Summary

graphite2 security update

Details

Graphite is a system that can be used to create “smart fonts” capable of displaying writing systems with various complex behaviors. A smart font contains not only letter shapes but also additional instructions indicating how to combine and position the letters in complex ways.

Security Fix(es):

Graphite before 1.3.15 has an integer underflow and resultant out-of-bounds write via Graphite actions, because slotat does not ensure that an offset is within the allowed slot-map range.(CVE-2026-50593)

Severity

7.3 (High)

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.
