Publication date

21 November 2006

Overview

OpenLDAP vulnerability

Releases

Details

Evgeny Legerov discovered that the OpenLDAP libraries did not correctly
truncate authcid names. This situation would trigger an assert and
abort the program using the libraries. A remote attacker could send
specially crafted bind requests that would lead to an LDAP server denial
of service.
