<title>Mailutils: Multiple vulnerabilities in imap4d and mail</title>
|
|
<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.

GNU Mailutils is a collection of mail-related utilities, including
|
|
an IMAP4 server (imap4d) and a Mail User Agent (mail).

<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>
|
|

<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.

<workaround>
|
|
<p>
|
|
There are no known workarounds at this time.

</workaround>
|
|
<resolution>
|
|
<p>
|
|
All GNU Mailutils users should upgrade to the latest available
|
|
version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=net-mail/mailutils-0.6-r1"</code>
