Red Hat, Inc. Security Advisory

Synopsis: Updated gnorpm packages are available for Red Hat Linux 6.1,
6.2, and 7.0
Advisory ID: RHSA-2000:072-08
Issue date: 2000-10-04
Updated on: 2000-11-27
Product: Red Hat Linux
Keywords: security tmp rpm
Cross references: N/A

1. Topic:

(This is a re-release of the previous errata caused by a missing patch).

A locally-exploitable security hole was found where a normal user could

trick root running GnoRPM into writing to arbitrary files due to a bug in

the gnorpm tmp file handling.

2000-11-27: Added packages for Red Hat Linux 7 for Alpha

2. Relevant releases/architectures:

Red Hat Linux 6.1 - i386, alpha, sparc
Red Hat Linux 6.2 - i386, alpha, sparc
Red Hat Linux 7.0 - i386, alpha

3. Problem description:

While fixing other problems with the gnorpm package, a locally-exploitable

security hole was found where a normal user could trick root running GnoRPM

into writing to arbitrary files due to a bug in the gnorpm tmp file


A new release of GnoRPM (0.95.1) is now available. This fixes a

significant number of bugs in the gnorpm package, including this security

hole. Administrators who use this program on multi-user machines should

update it, and anyone who uses it regularly will notice vast improvements.

All versions of GnoRPM before 0.95 are believed to be vulnerable.

4. Solution:

For each RPM for your particular architecture, run:

rpm -Fvh [filename]

where filename is the name of the RPM.

PLEASE NOTE: Due to library compatibility issues, this release of GnoRPM

0.95.1 cannot be used on a Red Hat Linux 6.0 system. If you are running

Red Hat Linux 6.0, to close this security hole you should abstain from

using GnoRPM until packages are available for that release. Alternatively

you may upgrade to a later version of Red Hat Linux. Packages that

function properly on a Red Hat Linux 6.0 system are in development.

5. Bug IDs fixed (http://bugzilla.redhat.com/bugzilla for more info):

6611 - GNORPM crashes when changing filter in the install window
6657 - gnorpm crashes
6659 - need summary
7678 - Corrupted .gnome/gnorpm.d/resources/fullIndex.rdf.gz
9254 - GnoRPM dies behind firewall
10162 - "Query" button in toolbar doesn't work properly
14327 - Querying RPMs after drag'n'drop crashes gnorpm

6. RPMs required:

Red Hat Linux 7.0:

These packages are GPG signed by Red Hat, Inc. for security. Our key
is available at:

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>
