CVE-2025-14017

Description

A flaw was found in curl. When performing multi-threaded LDAPS (Lightweight Directory Access Protocol Secure) transfers, changes to Transport Layer Security (TLS) options in one thread could inadvertently apply globally, affecting other concurrent transfers. This could lead to unintended security posture changes, such as disabling certificate verification for other threads. This vulnerability can result in a security bypass, where expected security checks are not performed.

Statement

This vulnerability is rated Moderate for Red Hat. The flaw in curl affects multi-threaded LDAPS transfers where changes to TLS options in one thread could inadvertently apply globally, impacting other concurrent transfers. This could lead to a security bypass if an application relies on specific TLS settings that are then overridden. Impact is limited to applications utilizing libcurl for multi-threaded LDAPS connections that dynamically modify TLS options.

Mitigation

Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.

Common Vulnerability Scoring System (CVSS) Score Details

Info alert:Important note

CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
