--------------------------------------------------------------------- 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 Issue date: 2000-10-04 Updated on: 2000-10-11 Product: Red Hat Linux Keywords: security tmp rpm Cross references: N/A --------------------------------------------------------------------- 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=20 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.
