RHSA-2020:0329

Vulnerability from csaf_redhat - Published: 2020-02-04 13:21 - Updated: 2026-06-28 12:15

Summary

Red Hat Security Advisory: go-toolset:rhel8 security update

Severity

Moderate

Scope

2 vulnerabilities in this advisory, including CVE-2019-16276.

CVE-2019-16276

It was discovered that net/http (through net/textproto) in golang does not correctly interpret HTTP requests where an HTTP header contains spaces before the colon. This could be abused by an attacker to smuggle HTTP requests when a proxy or a firewall is placed behind a server implemented in Go or to filter bypasses depending on the specific network configuration.

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.
