Red Hat, Inc. Red Hat Security Advisory
Synopsis: Updated scrollkeeper packages fix tempfile vulnerability
Advisory ID: RHSA-2002:186-07
Issue date: 2002-08-19
Updated on: 2002-08-28
Product: Red Hat Linux
Keywords: scrollkeeper tmpfile symlink
Cross references:
Obsoletes:
CVE Names: CAN-2002-0662
---------------------------------------------------------------------
1. Topic:
Updated scrollkeeper packages are now available for Red Hat Linux 7.3
which fix a tempfile vulnerability.
2. Relevant releases/architectures:
Red Hat Linux 7.3 - i386
3. Problem description:
ScrollKeeper is a cataloging system for documentation. All versions of
ScrollKeeper between 0.3 and 0.3.11 have a tempfile vulnerability.
The scrollkeeper-get-cl command generates temporary files in the /tmp
directory. These files are named scrollkeeper-tempfile.[0-4], and
while creating these files scrollkeeper-get-cl follows symbolic
links. These files are created when a user logs in to a GNOME session
and are created as the user who logged in. This means an attacker
with local access can easily create and overwrite files as another
user.
This errata updates ScrollKeeper packages for Red Hat Linux 7.3 with
patches that prevent ScrollKeeper from following symlinks when
creating temporary files. Previous releases of Red Hat Linux do not
contain vulnerable versions of Scrollkeeper.
Thanks go to Spybreak for discovering and responsibly disclosing this
vulnerability.
4. Solution:
Before applying this update, make sure all previously released errata
relevant to your system have been applied.
To update all RPMs for your particular architecture, run:
rpm -Fvh [filenames]
where [filenames] is a list of the RPMs you wish to upgrade. Only
those RPMs which are currently installed will be updated. Those RPMs
which are not installed but included in the list will not be updated.
Note that you can also use wildcards (*.rpm) if your current
directory *only* contains the desired RPMs.
Please note that this update is also available via Red Hat Network.
Many people find this an easier way to apply updates. To use Red Hat
Network, launch the Red Hat Update Agent with the following command:
up2date
This will start an interactive process that will result in the
appropriate RPMs being upgraded on your system.
5. RPMs required:
Red Hat Linux 7.3:
SRPMS:
ftp://updates.redhat.com/7.3/en/os/SRPMS/scrollkeeper-0.3.4-5.src.rpm
i386:
ftp://updates.redhat.com/7.3/en/os/i386/scrollkeeper-0.3.4-5.i386.rpm
6. Verification:
MD5 sum Package Name
--------------------------------------------------------------------------

392a5149a4b0e8abce9c350c88ee827a 7.3/en/os/i386/scrollkeeper-0.3.4-5.i386.rpm
These packages are GPG signed by Red Hat, Inc. for security. Our key
is available at:
http://www.redhat.com/about/contact/pgpkey.html
You can verify each package with the following command:
rpm --checksig <filename>
If you only wish to verify that each package has not been corrupted or
tampered with, examine only the md5sum with the following command:
rpm --checksig --nogpg <filename>
