<synopsis>
The imap4d server and the mail utility from GNU Mailutils contain multiple
vulnerabilities, potentially allowing a remote attacker to execute
arbitrary code with root privileges.

<background>
<p>
GNU Mailutils is a collection of mail-related utilities, including
an IMAP4 server (imap4d) and a Mail User Agent (mail).
</p>

<description>
<p>
infamous41d discovered several vulnerabilities in GNU Mailutils.
imap4d does not correctly implement formatted printing of command tags
(CAN-2005-1523), fails to validate the range sequence of the "FETCH"
command (CAN-2005-1522), and contains an integer overflow in the
"fetch_io" routine (CAN-2005-1521). mail contains a buffer overflow in
"header_get_field_name()" (CAN-2005-1520).
</p>
</description>
<impact type="high">
<p>
A remote attacker can exploit the format string and integer
overflow in imap4d to execute arbitrary code as the imap4d user, which
is usually root. By sending a specially crafted email message, a remote
attacker could exploit the buffer overflow in the "mail" utility to
execute arbitrary code with the rights of the user running mail.
Finally, a remote attacker can also trigger a Denial of Service by
sending a malicious FETCH command to an affected imap4d, causing
excessive resource consumption.
</p>
</impact>
<workaround>
<p>
There are no known workarounds at this time.
</p>
</workaround>
<resolution>
<p>
All GNU Mailutils users should upgrade to the latest available
version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=net-mail/mailutils-0.6-r1&quot;</code>
</resolution>
