patches for easier mirroring, to eliminate a special copy, to make www.freebsd.org/security a full copy of security.freebsd.org and be eventually be the same. For now files are just sitting there. The symlinks are missing. Discussed on: www (repository location) Discussed with: simon (so)

0. Revision History
|
|
|
|
v1.0 2002-01-04 Initial release
|
|
v1.1 2002-01-06 Corrected typo in mutt port version.
|
|
|
|
I. Background
|
|
|
|
Mutt is a small but very powerful text-based mail client for Unix
|
|
operating systems.
|
|
|
|
II. Problem Description
|
|
|
|
The mutt ports, versions prior to mutt-1.2.5_1 and
|
|
mutt-devel-1.3.24_2, contain a buffer overflow in the handling of
|
|
email addresses in headers.
|
|
|
|
The mutt and mutt-devel ports are not installed by default, nor are
|
|
they "part of FreeBSD" as such: they are parts of the FreeBSD ports
|
|
collection, which contains over 6000 third-party applications in a
|
|
ready-to-install format. The ports collection shipped with FreeBSD 4.4
|
|
contains this problem since it was discovered after the release.
|
|
|
|
FreeBSD makes no claim about the security of these third-party
|
|
applications, although an effort is underway to provide a security
|
|
audit of the most security-critical ports.
|
|
|
|
III. Impact
|
|
|
|
An attacker may send an email message with a specially crafted email
|
|
address in any of several message headers to the victim. When the
|
|
victim reads the message using mutt and encounters that email address,
|
|
the buffer overflow is triggered and may result in arbitrary code
|
|
being executed with the privileges of the victim.
|
|
|
|
IV. Workaround
|
|
|
|
1) Deinstall the mutt and mutt-devel ports/packages if you have them
|
|
installed.
|
|
|
|
V. Solution
|
|
|
|
1) Upgrade your entire ports collection and rebuild the ports.
|
|
|
|
2) Deinstall the old packages and install news package dated after the
|
|
correction date, obtained from the following directories:
|
|
|
|
[i386]
|
|
ftp://ftp.FreeBSD.org/pub/FreeBSD/ports/i386/packages-4-stable/mail/mutt-1.2.5_1.tgz
|
|
ftp://ftp.FreeBSD.org/pub/FreeBSD/ports/i386/packages-4-stable/mail/mutt-devel-1.3.24_2.tgz
|
|
ftp://ftp.FreeBSD.org/pub/FreeBSD/ports/i386/packages-5-current/mail/mutt-1.2.5_1.tgz
|
|
ftp://ftp.FreeBSD.org/pub/FreeBSD/ports/i386/packages-5-current/mail/mutt-devel-1.3.24_2.tgz
|
|
|
|
[alpha]
|
|
Packages are not automatically generated for the alpha architecture at
|
|
this time due to lack of build resources.
|
|
|
|
NOTE: It may be several days before updated packages are available.
|
|
|
|
3) Download a new port skeleton for the mutt or mutt-devel port from:
|
|
|
|
http://www.freebsd.org/ports/
|
|
|
|
and use it to rebuild the port.
|
|
|
|
4) Use the portcheckout utility to automate option (3) above. The
|
|
portcheckout port is available in /usr/ports/devel/portcheckout or the
|
|
package can be obtained from:
|
|
|
|
ftp://ftp.FreeBSD.org/pub/FreeBSD/ports/i386/packages-4-stable/devel/portcheckout-2.0.tgz
|
|
ftp://ftp.FreeBSD.org/pub/FreeBSD/ports/i386/packages-5-current/devel/portcheckout-2.0.tgz
