Description:
Two security issues have been reported in HP TCP/IP Services for OpenVMS, which can be exploited by malicious people to disclose sensitive information or to conduct brute force attacks.

1) The security issue is caused due to the POP server returning different responses depending on whether or not a valid user name is supplied and can be exploited to enumerate valid POP user names.

2) The problem is that the TCP/IP Services POP3 mail mechanism is not utilising the intrusion detection of OpenVMS properly. This can be exploited to conduct brute force attacks.

The security issues are reported in TCP/IP Services 5.6. Other versions may also be affected.

Solution:
Grant only trusted people network access to the POP service.
