Description OSIDB Bzimport 2026-10-02 10:22:00 UTC 
Asymmetric Resource Consumption vulnerability in Apache Directory LDAP API.



A LDAP server using the LDAP API (like Apache DS) may consume 100% of a CPU core indefinitely when processing some badly crafted Telephone Numbers.



This issue affects Apache Directory LDAP API: from 2.1.0 before 2.1.9.



Users are recommended to upgrade to version 2.1.9, which fixes the issue.
