Vulnerability from osv_openeuler – Published: 2023-09-11 11:06 – Updated: 2026-08-06 11:06 – Source website

Summary

libtommath security update

Details

LibTomMath is a free open source portable number theoretic multiple-precision integer library written entirely in C. The library is designed to provide a simple to work with API that provides fairly efficient routines that build out of the box without configuration.

Security Fix(es):

Integer Overflow vulnerability in mp_grow in libtom libtommath before commit beba892bc0d4e4ded4d667ab1d2a94f4d75109a9, allows attackers to execute arbitrary code and cause a denial of service (DoS).(CVE-2023-36328)

Severity

9.8 (Critical)

Detection rules are retrieved from Rulezet.

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.
