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)

FreeBSD-SA-01:50 Security Advisory

FreeBSD, Inc.
|
|
|
|
Topic: windowmaker contains possibly exploitable buffer overflow
|
|
|
|
Category: ports
|
|
Module: windowmaker/windowmaker-i18n
|
|
Announced: 2001-07-27
|
|
Credits: Robert Marshall <robert@chezmarshall.freeserve.co.uk>
|
|
Affects: Ports collection prior to the correction date.
|
|
Corrected: 2001-07-24
|
|
Vendor status: Updated version released
|
|
FreeBSD only: NO
|
|
|
|
I. Background
|
|
|
|
Windowmaker is a GNUstep-compliant X11 window manager which emulates
|
|
the NeXTSTEP interface.
|
|
|
|
II. Problem Description
|
|
|
|
The windowmaker ports, versions prior to windowmaker-0.65.0_2 and
|
|
windowmaker-i18n-0.65.0_1, contain a potentially exploitable buffer
|
|
overflow when displaying a very long window title in the window list
|
|
menu. Since programs such as web browsers will include the contents
|
|
of a webpage's title tag in window titles, this problem may allow
|
|
authors of malicious webpages to cause windowmaker to crash and
|
|
potentially execute arbitrary code as the user running windowmaker.
|
|
|
|
The windowmaker ports are not installed by default, nor are they
|
|
"part of FreeBSD" as such: they are part of the FreeBSD ports
|
|
collection, which contains over 5500 third-party applications in
|
|
a ready-to-install format. The ports collection shipped with FreeBSD
|
|
4.3 is vulnerable to this problem since it was discovered after
|
|
its 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
|
|
|
|
Under certain circumstances, remote webservers may cause windowmaker
|
|
to crash and potentially execute arbitrary code as the user running
|
|
windowmaker.
|
|
|
|
If you have not chosen to install the windowmaker port/package,
|
|
then your system is not vulnerable to this problem.
|
|
|
|
IV. Workaround
|
|
|
|
Deinstall the windowmaker package if you have installed it.
|
|
|
|
V. Solution
|
|
|
|
One of the following:
|
|
|
|
1) Upgrade your entire ports collection and rebuild the windowmaker
|
|
or windowmaker-i18n port.
|
|
|
|
2) Deinstall the old package and install a new package dated after the
|
|
correction date, obtained from the following directories:
|
|
|
|
[i386]
|
|
ftp://ftp.FreeBSD.org/pub/FreeBSD/ports/i386/packages-4-stable/x11-wm/windowmaker-0.65.1.tgz
|
|
ftp://ftp.FreeBSD.org/pub/FreeBSD/ports/i386/packages-5-current/x11-wm/windowmaker-0.65.1.tgz
|
|
ftp://ftp.FreeBSD.org/pub/FreeBSD/ports/i386/packages-4-stable/x11-wm/windowmaker-i18n-0.65.0_1.tgz
|
|
ftp://ftp.FreeBSD.org/pub/FreeBSD/ports/i386/packages-5-current/x11-wm/windowmaker-i18n-0.65.0_1.tgz
|
|
|
|
[alpha]
|
|
Packages are not automatically generated for the alpha architecture at
|
|
this time due to lack of build resources.
|
|
|
|
3) download a new port skeleton for the windowmaker or windowmaker-i18n
|
|
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
