Red Hat Security Advisory Synopsis: Updated gnupg packages available Advisory ID: RHSA-2001:063-02 Issue date: 2001-05-02 Updated on: 2001-05-16 Product: Red Hat Linux Keywords: gnupg klima rosa Cross references: Obsoletes: RHSA-2000:131 --------------------------------------------------------------------- 1. Topic: Updated gnupg packages are now available for Red Hat Linux 6.2, 7, and 7.1. These updates address a potential vulnerability which could allow an attacker to compute a user's secret key. 2. Relevant releases/architectures: Red Hat Linux 6.2 - alpha, i386, sparc Red Hat Linux 7.0 - alpha, i386 Red Hat Linux 7.1 - i386 3. Problem description: By modifying an unsuspecting user's private keyring, an attacker can cause a user to generate incorrect signatures for data. If a user generates both a correct and an incorrect signature for the same data, the different signatures can be used to compute the user's secret key. 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. Bug IDs fixed (http://bugzilla.redhat.com/bugzilla for more info): 33473 - secret keyring compromise leading to secret key disclosure 6.
