Summary

poppler security update

Details

is a PDF rendering library.

Security Fix(es):

Poppler is a PDF rendering library. Versions prior to 25.06.0 use std::atomic_int for reference counting. Because std::atomic_int is only 32 bits, it is possible to overflow the reference count and trigger a use-after-free. Version 25.06.0 patches the issue.(CVE-2025-52886)

Severity

4.0 (Medium)

CVE-2025-52886 (GCVE-0-2025-52886)

Vulnerability from cvelistv5 – Published: 2025-07-02 15:46 – Updated: 2025-11-04 22:06

Title

Poppler Use After Free Vulnerability

Summary

Poppler is a PDF rendering library. Versions prior to 25.06.0 use `std::atomic_int` for reference counting. Because `std::atomic_int` is only 32 bits, it is possible to overflow the reference count and trigger a use-after-free. Version 25.06.0 patches the issue.

Severity

5.5 (Medium)

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.
