Vulnerability from osv_openeuler – Published: 2023-11-17 11:06 – Updated: 2026-08-06 11:06 – Source website

Summary

zziplib security update

Details

The zziplib is a lightweight library to easily extract data from zip files. Applications can bundle files into a single zip archive and access them. The implementation is based only on the (free) subset of compression with the zlib algorithm which is actually used by the zip/unzip tools.

Security Fix(es):

An issue was discovered in function zzip_disk_entry_to_file_header in mmapped.c in zziplib 0.13.69, which will lead to a denial-of-service.(CVE-2020-18770)

Severity

5.5 (Medium)

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.
