CVE-2025-14017  (opens in a new tab)

How to fix?

Upgrade Ubuntu:20.04 curl to version 7.68.0-1ubuntu2.25+esm2 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream curl package and not the curl package as distributed by Ubuntu. See How to fix? for Ubuntu:20.04 relevant fixed versions and status.

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.
