Race condition In curl
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.
Mitigation
Update Impact
Minimal update. May introduce new vulnerabilities or breaking changes.
