DESCRIPTION
Pine is a mail and news text based client developed by the Washington
University[1].

Linus Sjöberg (lsjoberg (at) aland (dot) net [email concealed]) discovered[2] a vulnerability that
allows an attacker to send a fully legal e-mail message with the
"From:" header crafted in such a way that will crash pine on
startup.

By exploiting this, an attacker can prevent the pine user of starting
the program to manage his/her mailbox. It was not confirmed if it is
possible to execute arbitrary code by exploiting this vulnerability,
but such a possibility exists.

The Common Vulnerabilities and Exposures project (cve.mitre.org) has
assigned[3] the name CAN-2002-1320 to this issue.

Please notice that this new version of pine (4.50) includes several
new features and other bugfixes, as documented in the official
changelog[4].

SOLUTION
All pine users should upgrade.
