CommuniGate Pro Core Server before 5.0.7 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via LDAP messages with negative BER lengths, and possibly other vectors, as demonstrated by the ProtoVer LDAP test suite.

According to its banner, the version of CommuniGate Pro running on the remote host will crash when certain mail clients try to open an empty mailbox.  Remote code execution may even be possible.

The remote host appears to be running CommuniGate Pro, a commercial email and groupware application.  The version of CommuniGate Pro installed on the remote host includes an LDAP server that reportedly fails to handle malformed LDAP requests.  A user can leverage this issue to crash not just the LDAP server but also the entire application on the remote host.
