IBM Tivoli Directory Server SASL Bind Request Buffer Overflow (uncredentialed check)

This script is Copyright (C) 2011-2013 Tenable Network Security, Inc.


Synopsis :

The remote LDAP server is vulnerable to a buffer overflow attack.

Description :

Based on the response to a malformed LDAP bind request, it appears that
the installed version of IBM Tivoli Directory Server running on the
remote host is affected by a remote buffer overflow vulnerability.

A malicious LDAP request could cause a buffer overrun in the server,
potentially allowing an unauthenticated remote attacker to execute
arbitrary code within Tivoli Directory Server's server process. This
vulnerability has only been recreated on 32 bit platforms. (IO14010,
IO14013, IO14028, IO14046, IO14045).

Note that only IBM Tivoli Directory Server installs running on a 32-bit
platform are known to be affected.
