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-00:74 Security Advisory
|
|
FreeBSD, Inc.
|
|
|
|
Topic: gaim remote vulnerability
|
|
|
|
Category: ports
|
|
Module: gaim
|
|
Announced: 2000-11-20
|
|
Credits: Stan Bubrouski <stan@CCS.NEU.EDU>
|
|
Affects: Ports collection prior to the correction date.
|
|
Corrected: 2000-11-16
|
|
Vendor status: Updated version released
|
|
FreeBSD only: NO
|
|
|
|
I. Background
|
|
|
|
gaim is a popular AOL Instant Messenger client.
|
|
|
|
II. Problem Description
|
|
|
|
The gaim port, versions prior to 0.10.3_1, allows a client-side
|
|
exploit through a buffer overflow in the HTML parsing code. This
|
|
vulnerability may allow remote users to execute arbitrary code as the
|
|
user running gaim.
|
|
|
|
The gaim port is not installed by default, nor is it "part of FreeBSD"
|
|
as such: it is part of the FreeBSD ports collection, which contains
|
|
over 4100 third-party applications in a ready-to-install format. The
|
|
ports collections shipped with FreeBSD 3.5.1 and 4.1.1 contain this
|
|
problem since it was discovered after the releases, but it was
|
|
corrected prior to the release of FreeBSD 4.2.
|
|
|
|
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
|
|
|
|
Malicious remote users may execute arbitrary code as the user running
|
|
gaim.
|
|
|
|
If you have not chosen to install the gaim port/package, then your
|
|
system is not vulnerable to this problem.
|
|
|
|
IV. Workaround
|
|
|
|
Deinstall the gaim port/package, if you you have installed it.
|
|
|
|
V. Solution
|
|
|
|
One of the following:
|
|
|
|
1) Upgrade your entire ports collection and rebuild the gaim port.
|
|
|
|
2) Deinstall the old package and install a new package dated after the
|
|
correction date, obtained from:
|
|
|
|
ftp://ftp.FreeBSD.org/pub/FreeBSD/ports/i386/packages-3-stable/net/gaim-0.10.3_1.tgz
|
|
ftp://ftp.FreeBSD.org/pub/FreeBSD/ports/i386/packages-4-stable/net/gaim-0.10.3_1.tgz
|
|
ftp://ftp.FreeBSD.org/pub/FreeBSD/ports/alpha/packages-4-stable/net/gaim-0.10.3_1.tgz
|
|
ftp://ftp.FreeBSD.org/pub/FreeBSD/ports/i386/packages-5-current/net/gaim-0.10.3_1.tgz
|
|
ftp://ftp.FreeBSD.org/pub/FreeBSD/ports/alpha/packages-5-current/net/gaim-0.10.3_1.tgz
|
|
|
|
NOTE: It may be several days before updated packages are available.
|
|
|
|
3) download a new port skeleton for the gaim 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-3-stable/devel/portcheckout-2.0.tgz
|
|
ftp://ftp.FreeBSD.org/pub/FreeBSD/ports/i386/packages-4-stable/devel/portcheckout-2.0.tgz
|
|
ftp://ftp.FreeBSD.org/pub/FreeBSD/ports/alpha/packages-4-stable/devel/portcheckout-2.0.tgz
|
|
