Description OSIDB Bzimport 2026-10-02 10:01:47 UTC 
Stack Overflow vulnerability in Apache Directory LDAP API.



Before binding, a client can send a deeply nested search filter that overflows the stack in the server's decoder.



This issue affects Apache Directory LDAP API: from 1.2.0 before 1.2.9.



Users are recommended to upgrade to version 1.2.9, which fixes the issue.
