OESA-2024-1481 (CVE-2023-46049)

Vulnerability from osv_openeuler – Published: 2024-04-19 11:06 – Updated: 2026-08-06 11:06 – Source website

Summary

llvm security update

Details

LLVM is a compiler infrastructure designed for compile-time, link-time, runtime, and idle-time optimization of programs from arbitrary programming languages.

Security Fix(es):

LLVM 15.0.0 has a NULL pointer dereference in the parseOneMetadata() function via a crafted pdflatex.fmt file (or perhaps a crafted .o file) to llvm-lto. NOTE: this is disputed because the relationship between pdflatex.fmt and any LLVM language front end is not explained, and because a crash of the llvm-lto application should be categorized as a usability problem.(CVE-2023-46049)

Severity

7.5 (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.
