CVE-2025-14017

Published: 2026-01-08 10:15:46
Last Modified: 2026-01-27 21:29:40
Source: 2499f714-1537-4658-8207-48ae4bb9eae9

Description

When doing multi-threaded LDAPS transfers (LDAP over TLS) with libcurl, changing TLS options in one thread would inadvertently change them globally and therefore possibly also affect other concurrently setup transfers. Disabling certificate verification for a specific transfer could unintentionally disable the feature for other threads as well.
