GLSA-200505-20 : Mailutils: Multiple vulnerabilities in imap4d and mail

This script is Copyright (C) 2005-2015 Tenable Network Security, Inc.

Synopsis :

The remote Gentoo host is missing one or more security-related

Description :

The remote host is affected by the vulnerability described in GLSA-200505-20
(Mailutils: Multiple vulnerabilities in imap4d and mail)

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).

Impact :

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 :

There are no known workarounds at this time.

Solution :

# emerge --sync
# emerge --ask --oneshot --verbose '>=net-mail/mailutils-0.6-r1'
