-----BEGIN PGP SIGNED MESSAGE----- =========================================================================== AUSCERT External Security Bulletin Redistribution ESB-2001.508 -- RHSA-2001:150-06 Updated Cyrus SASL packages available 30 November 2001 =========================================================================== AusCERT Security Bulletin Summary --------------------------------- Product: Cyrus-SASL Vendor: Red Hat Operating System: Red Hat Linux 7.0 Red Hat Linux 7.1 Red Hat Linux 7.2 Platform: Alpha i386 IA-64 Impact: Reduced Security Denial of Service Access Required: Remote - --------------------------BEGIN INCLUDED TEXT-------------------- - --------------------------------------------------------------------- Red Hat, Inc. Red Hat Security Advisory Synopsis: Updated Cyrus SASL packages available Advisory ID: RHSA-2001:150-06 Issue date: 2001-11-02 Updated on: 2001-11-29 Product: Red Hat Linux Keywords: cyrus sasl syslog format string Cross references: RHSA-2001:151 Obsoletes: RHSA-2000:094 - --------------------------------------------------------------------- 1. Topic: Updated Cyrus-SASL packages are now available for Red Hat Linux 7, 7.1, and 7.2. These packages fix a possible format-string vulnerability in the default logging callback function provided by libsasl. 2. Relevant releases/architectures: Red Hat Linux 7.0 - alpha, i386 Red Hat Linux 7.1 - alpha, i386, ia64 Red Hat Linux 7.2 - i386 3. Problem description: The default logging callback function supplied by the Cyrus SASL library suffers from a format-string vulnerability. This function is used when a server which uses Cyrus SASL attempts to set or change a user's secrets. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2001-0869 to this issue. 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): 43079 - Split CRAM-MD5 and Digest-MD5 from main package 6.
