Vulnerability from osv_openeuler – Published: 2023-02-03 11:05 – Updated: 2026-08-06 11:05 – Source website

Summary

pkgconf security update

Details

pkgconf is a program which helps to configure compiler and linker flags for development frameworks. It is similar to pkg-config from freedesktop.org, providing additional functionality while also maintaining compatibility.

Security Fix(es):

In pkgconf through 1.9.3, variable duplication can cause unbounded string expansion due to incorrect checks in libpkgconf/tuple.c:pkgconf_tuple_parse. For example, a .pc file containing a few hundred bytes can expand to one billion bytes.(CVE-2023-24056)

Severity

9.8 (Critical)

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.

Vulnerabilities whose description is nearest to this one in the vector space of the CIRCL/vulnerability-attack-technique-biencoder model. This is a similarity search over the bi-encoder space (plain cosine), not a classification, and it has no measured accuracy.
