--------------------------------------------------------------------- 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
handling.
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

These packages are GPG signed by Red Hat, Inc. for security. Our key is available at: http://www.redhat.com/corp/contact.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>
