FreeBSD Security Advisory - The pine4 port, versions 4.21 and before, contains a buffer overflow vulnerability which allows a remote user to execute arbitrary code on the local client by the sending of a special-crafted email message. The overflow occurs during the periodic "new mail" checking of an open folder.
