iDEFENSE Security Advisory 05.25.05-3 - Remote exploitation of an input validation in the FETCH command of the imap4d server from the GNU Project's Mailutils package error may allow an authenticated remote attacker to perform a denial of service against an affected system. iDEFENSE Labs has verified the existence of this vulnerability in versions 0.5 and 0.6 of the GNU Mailutils package. It is suspected that any previous versions which contain the imap4d server are also affected.

GNU Mailutils 0.6 imap4d FETCH Command Resource Consumption DoS
Vulnerability

iDEFENSE Security Advisory 05.25.05
http://www.idefense.com/application/poi/display?type=vulnerabilities
May 25, 2005

I. BACKGROUND

The GNU mailutils package is a collection of mail-related
utilities, including local and remote mailbox access services.
More information is available at the following site:

    http://www.gnu.org/software/mailutils/mailutils.html

II. DESCRIPTION

Remote exploitation of an input validation in the FETCH command
of the imap4d server from the GNU Project's Mailutils package
error may allow an authenticated remote attacker to perform a
denial of service against an affected system.

The imap4d server allows remote users to retrieve their email
via the Internet Message Access Protocol, Version 4rev1 as
specified in RFC3501. This is a client/server protocol supported
by a large number of email clients on multiple platforms.

The vulnerability specifically exists in the handling of the
sequence range agument to the FETCH command. A sequence range
such as 1:4294967294 will cause the the spawned instance of the
server to enter what is effectively an infinite loop, allocating
memory on each cycle.

III. ANALYSIS

Successful exploitation of the vulnerability would allow a
remote authenticated used to cause the system hosting the imap4d
to become unresponsive due to lack of memory resources. On some
operating systems, such as Linux, processes will be killed by
the kernel out of memory manager.

IV. DETECTION

iDEFENSE Labs has verified the existance of this vulnerability
in versions 0.5 and 0.6 of the GNU Mailutils package. It is
suspected that any previous versions which contain the imap4d
server are also affected.

V. WORKAROUND

iDEFENSE is currently unaware of any effective workarounds for
this issue. Access to the affected host should be filtered at
the network boundary if global accessibility is not required.
Restricting access to only trusted hosts and networks may reduce
the likelihood of exploitation.

Applying resource limits on the memory avaialable to the imap4d
process will cause the spawned instance of the server to exit
when it reaches the limit. Information on how to to perform this
operation is operating system dependant, and may cause some
normal operations, especially on large messages, to fail.

VI. VENDOR RESPONSE

This vulnerability has been fixed in GNU mailutils 0.6.90 which is
available for download at:

   ftp://alpha.gnu.org/gnu/mailutils/

VII. CVE INFORMATION

The Common Vulnerabilities and Exposures (CVE) project has assigned the
name CAN-2005-1522 to this issue. This is a candidate for inclusion in
the CVE list (http://cve.mitre.org), which standardizes names for
security problems.

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
==========

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

Affected packages
=================

    -------------------------------------------------------------------
     Package             /  Vulnerable  /                   Unaffected
    -------------------------------------------------------------------
  1  net-mail/mailutils      < 0.6-r1                        >= 0.6-r1

Description
===========

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.

Resolution
==========

All GNU Mailutils users should upgrade to the latest available version:

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

"infamous41md" discovered several vulnerabilities in the GNU mailutils
package which contains utilities for handling mail.  These problems
can lead to a denial of service or the execution of arbitrary code.
The Common Vulnerabilities and Exposures project identifies the
following vulnerabilities.

CAN-2005-1520

    Buffer overflow mail header handling may allow a remote attacker
    to execute commands with the privileges of the targeted user.

CAN-2005-1521

    Combined integer and heap overflow in the fetch routine can lead
    to the execution of arbitrary code.

CAN-2005-1522

    Denial of service in the fetch routine.

CAN-2005-1523

    Format string vulnerability can lead to the execution of arbitrary
    code.

For the stable distribution (woody) these problems have been fixed in
version 20020409-1woody2.

For the testing distribution (sarge) these problems have been fixed in
version 0.6.1-4.

For the unstable distribution (sid) these problems have been fixed in
version 0.6.1-4.

We recommend that you upgrade your mailutils packages.
