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-2000:072-05

1. Topic:
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.
2. Relevant releases/architectures:
Red Hat Linux 6.1 - i386, alpha, sparc
Red Hat Linux 6.2 - i386, alpha, sparc
Red Hat Linux 6.2EE - i386
Red Hat Linux 7.0 - i386
Red Hat Linux 7.0J - i386
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

9254 - GnoRPM dies behind firewall
10162 - "Query" button in toolbar doesn't work properly
14327 - Querying RPMs after drag'n'drop crashes gnorpm
