Vulnerability from osv_openeuler – Published: 2022-05-28 11:04 – Updated: 2026-08-06 11:04 – Source website

Summary

curl security update

Details

cURL is a computer software project providing a library (libcurl) and command-line tool (curl) for transferring data using various protocols.

Security Fix(es):

libcurl would reuse a previously created connection even when a TLS or SSH related option had been changed that should have prohibited reuse. libcurl keeps previously used connections in a connection pool for subsequent transfers to reuse if one of them matches the setup. However, several TLS and SSH settings were left out from the configuration match checks, making them match too easily.(CVE-2022-27782)

A vulnerability was found in curl. This issue occurs due to an erroneous function. A malicious server could make curl within Network Security Services (NSS) get stuck in a never-ending busy loop when trying to retrieve that information. This flaw allows an Infinite Loop, affecting system availability.(CVE-2022-27781)

Severity

6.0 (Medium)

CVE-2022-27782 (GCVE-0-2022-27782)

Vulnerability from cvelistv5 – Published: 2022-06-01 00:00 – Updated: 2026-05-27 13:33

Summary

libcurl would reuse a previously created connection even when a TLS or SSHrelated option had been changed that should have prohibited reuse.libcurl keeps previously used connections in a connection pool for subsequenttransfers to reuse if one of them matches the setup. However, several TLS andSSH settings were left out from the configuration match checks, making themmatch too easily.

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.
