MailServer, which potentially can be exploited by malicious people to
compromise a vulnerable system.

handling of the POP3 USER command. This can be exploited to cause a
heap-based buffer overflow and may allow arbitrary code execution via
an overly long user name passed to the command.

may also be affected.
