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-00:50 Security Advisory

|
Topic: listmanager port allows local root compromise
|
|
|
|
Category: ports
|
|
Module: listmanager
|
|
Announced: 2000-09-13
|
|
Affects: Ports collection.
|
|
Corrected: 2000-09-08
|
|
Credits: Discovered during internal auditing
|
|
Vendor status: Updated version released.
|
|
FreeBSD only: NO
|
|
|
|
I. Background
|
|
|
|
Listmanager is a mailing list manager.
|
|
|
|
II. Problem Description
|
|
|
|
The listmanager port, versions prior to 2.105.1, contained several
|
|
locally exploitable buffer overflow vulnerabilities which could be
|
|
used to gain root privileges.
|
|
|
|
Since the source code to listmanager is not available, it is difficult
|
|
to determine whether there are remaining security vulnerabilities, or
|
|
whether the software was previously exploitable remotely, but we
|
|
believe the author has made a good faith effort to improve the
|
|
security of the code.
|
|
|
|
The listmanager 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 3800 third-party applications in a ready-to-install
|
|
format. The ports collections shipped with FreeBSD 4.1 and 3.5.1
|
|
contain this problem since it was discovered after the releases.
|
|
|
|
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
|
|
|
|
Unprivileged users can obtain root privileges on the local system.
|
|
|
|
If you have not chosen to install the listmanager port/package, then
|
|
your system is not vulnerable to this problem.
|
|
|
|
IV. Workaround
|
|
|
|
Deinstall the listmanager port/package, if you have installed it.
|
|
|
|
V. Solution
|
|
|
|
One of the following:
|
|
|
|
1) Upgrade your entire ports collection and rebuild the listmanager 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/mail/listmanager-2.105.1.tgz
|
|
ftp://ftp.FreeBSD.org/pub/FreeBSD/ports/i386/packages-4-stable/mail/listmanager-2.105.1.tgz
|
|
ftp://ftp.FreeBSD.org/pub/FreeBSD/ports/alpha/packages-4-stable/mail/listmanager-2.105.1.tgz
|
|
ftp://ftp.FreeBSD.org/pub/FreeBSD/ports/i386/packages-5-current/mail/listmanager-2.105.1.tgz
|
|
ftp://ftp.FreeBSD.org/pub/FreeBSD/ports/alpha/packages-5-current/mail/listmanager-2.105.1.tgz
|
|
|
|
NOTE: It may be several days before updated packages are available.
|
|
|
|
3) download a new port skeleton for the listmanager 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
|
|
ftp://ftp.FreeBSD.org/pub/FreeBSD/ports/i386/packages-5-current/devel/portcheckout-2.0.tgz
