-- Vulnerability Details:
This vulnerability allows remote attackers to execute arbitrary code on
systems with vulnerable installations of IBM Lotus Domino.
Authentication is not required to exploit this vulnerability.

The specific flaw exists within the POP3 and IMAP services while
processing malformed e-mails. The vulnerable code expands specific
non-printable characters within a "mail from" command without allocating
adequate space. By providing enough of these characters, memory can be
corrupted leading to arbitrary code execution under the context of the
SYSTEM user.
