-----BEGIN PGP SIGNED MESSAGE----- =========================================================================== AUSCERT External Security Bulletin Redistribution ESB-2001.395 -- RHSA-2001:109-05 Updated xinetd package available for Red Hat Linux 7 and 7.1 11 September 2001 =========================================================================== AusCERT Security Bulletin Summary --------------------------------- Product: xinetd Vendor: Red Hat Operating System: Red Hat Linux 7.0 Red Hat Linux 7.1 Platform: Alpha i386 IA-64 Impact: Denial of Service - --------------------------BEGIN INCLUDED TEXT-------------------- - --------------------------------------------------------------------- Red Hat, Inc. Red Hat Security Advisory Synopsis: Updated xinetd package available for Red Hat Linux 7 and 7.1 Advisory ID: RHSA-2001:109-05 Issue date: 2001-08-31 Updated on: 2001-09-07 Product: Red Hat Linux Keywords: xinetd memset segfault audit Cross references: Obsoletes: RHSA-2001:092 - --------------------------------------------------------------------- 1. Topic: A security audit has been done by Solar Designer on xinetd, and the results are now being made available as a preemptive measure. 2. Relevant releases/architectures: Red Hat Linux 7.0 - alpha, i386 Red Hat Linux 7.1 - alpha, i386, ia64 3. Problem description: A security audit has been done by Solar Designer on xinetd, and the results are now being made available as a preemptive measure. Also, memsetting too much memory to 0 would eventually lead to segfaults when executing services. This internal bug was fixed. 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): 48367 - telnet service fails after a couple of hours with xinetd-2.3.0 51737 - xinetd does not register all rpc versions with the portmapper 6.
