-----BEGIN PGP SIGNED MESSAGE----- =========================================================================== AUSCERT External Security Bulletin Redistribution ESB-2003.0373 -- RHSA-2003:175-01 Updated gnupg packages fix validation bug 21 May 2003 =========================================================================== AusCERT Security Bulletin Summary --------------------------------- Product: gnupg Publisher: Red Hat Operating System: Red Hat Linux 9 Red Hat Linux 8.0 Red Hat Linux 7.3 Red Hat Linux 7.2 Red Hat Linux 7.1 Linux Impact: Reduced Security Access Required: Existing Account CVE Names: CAN-2003-0255 - --------------------------BEGIN INCLUDED TEXT-------------------- - --------------------------------------------------------------------- Red Hat Security Advisory Synopsis: Updated gnupg packages fix validation bug Advisory ID: RHSA-2003:175-01 Issue date: 2003-05-20 Updated on: 2003-05-20 Product: Red Hat Linux Keywords: gnupg trust UID Cross references: Obsoletes: RHSA-2001:073 CVE Names: CAN-2003-0255 - --------------------------------------------------------------------- 1. Topic: Updated gnupg packages correcting a bug in the GnuPG key validation functions are now available. 2. Relevant releases/architectures: Red Hat Linux 7.1 - i386 Red Hat Linux 7.2 - i386, ia64 Red Hat Linux 7.3 - i386 Red Hat Linux 8.0 - i386 Red Hat Linux 9 - i386 3. Problem description: The GNU Privacy Guard (GnuPG) is a utility for encrypting data and creating digital signatures. When evaluating trust values for different UIDs assigned to a given key, GnuPG versions earlier than 1.2.2 would incorrectly associate the trust value of the UID with the highest trust value with every UID assigned to that key. This would prevent an expected warning message from being generated. All users are advised to upgrade to these errata packages which include patches from the GnuPG development team that correct this issue for GnuPG versions 1.0.7 and 1.2.1. This update also upgrades Red Hat Linux 7.1, 7.2, and 7.3 users to GnuPG version 1.0.7. 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.
