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-01:21 Security Advisory
|
|
FreeBSD, Inc.
|
|
|
|
Topic: ja-elvis and ko-helvis ports contain a local
|
|
root compromise
|
|
|
|
Category: ports
|
|
Module: ja-elvis/ko-helvis
|
|
Announced: 2001-02-07
|
|
Credits: Found during internal auditing
|
|
Affects: Ports collection prior to the correction date.
|
|
Corrected: 2001-01-28
|
|
Vendor status: Vendor notified
|
|
FreeBSD only: No
|
|
|
|
I. Background
|
|
|
|
The ja-elvis and ko-helvis ports are localized versions of elvis,
|
|
a vi editor clone.
|
|
|
|
II. Problem Description
|
|
|
|
The ja-elvis and ko-helvis ports, versions prior to ja-elvis-1.8.4_1
|
|
and ko-helvis-1.8h2_1, contain an exploitable buffer overflow in the
|
|
elvrec utility. Because elvrec is setuid root, unprivileged local
|
|
users may gain root privileges on the local system.
|
|
|
|
The ja-elvis and ko-helvis 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 4500 third-party applications
|
|
in a ready-to-install format. The ports collections shipped with
|
|
FreeBSD 3.5.1 and 4.2 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 local users may gain root privileges on the local
|
|
system.
|
|
|
|
If you have not chosen to install the ja-elvis or ko-helvis
|
|
ports/packages, then your system is not vulnerable to this problem.
|
|
|
|
IV. Workaround
|
|
|
|
Deinstall the ja-elvis or ko-helvis port/package, if you have
|
|
installed it.
|
|
|
|
V. Solution
|
|
|
|
One of the following:
|
|
|
|
1) Upgrade your entire ports collection and rebuild the ja-elvis or
|
|
ko-helvis port.
|
|
|
|
2) Deinstall the old package and install a new package dated after the
|
|
correction date, obtained from:

[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 ja-elvis or ko-helvis 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
