DESCRIPTION:
Evgeny Legerov has discovered a vulnerability in Sun Java System
Directory Server, which can be exploited by malicious people to cause
a DoS (Denial of Service).

The vulnerability is caused due to an error in the LDAP server within
the handling of certain requests. This can be exploited to crash the
service via a specially-crafted request sent to the LDAP server
port.

The vulnerability has been confirmed in version 5.2 P4. Other
versions may also be affected.

Restrict access to the LDAP service.
