Ubuntu Security Notice USN-384-1
20th November, 2006
openldap2.2 vulnerability
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 6.10
- Ubuntu 6.06 LTS
- Ubuntu 5.10
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.
