OESA-2022-1756 (CVE-2020-25219)

Vulnerability from osv_openeuler – Published: 2022-07-22 11:05 – Updated: 2026-08-06 11:05 – Source website

Summary

libproxy security update

Details

libproxy offers the following features: extremely small core footprint (< 35k). no external dependencies within libproxy core.(libproxy plugins may have dependencies). only 3 functions in the stable external API. dynamic adjustment to changing network topology.* a standard way of dealing with proxy settings across all scenarios.

Security Fix(es):

url::recvline in url.cpp in libproxy 0.4.x through 0.4.15 allows a remote HTTP server to trigger uncontrolled recursion via a response composed of an infinite stream that lacks a newline character. This leads to stack exhaustion.(CVE-2020-25219)

Severity

7.5 (High)

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.
