-----BEGIN PGP SIGNED MESSAGE----- =========================================================================== AUSCERT External Security Bulletin Redistribution ESB-2001.476 -- RHSA-2001:144-04 Updated iptables packages are available 9 November 2001 =========================================================================== AusCERT Security Bulletin Summary --------------------------------- Product: iptables Vendor: Red Hat Operating System: Red Hat Linux 7.1 Red Hat Linux 7.2 Platform: Alpha i386 Impact: Denial of Service Reduced Security - --------------------------BEGIN INCLUDED TEXT-------------------- - --------------------------------------------------------------------- Red Hat, Inc. Red Hat Security Advisory Synopsis: Updated iptables packages are available Advisory ID: RHSA-2001:144-04 Issue date: 2001-10-30 Updated on: 2001-11-05 Product: Red Hat Linux Keywords: iptables firewall logging Cross references: Obsoletes: - --------------------------------------------------------------------- 1. Topic: A new version of iptables fixing various minor security problems and some other bugs is available. 2. Relevant releases/architectures: Red Hat Linux 7.1 - alpha, i386 Red Hat Linux 7.2 - i386 3. Problem description: Some problems in earlier releases of iptables could lead to bad iptables-save files, causing the firewall not to come up when iptables was restarted (e.g. at system reboot). This release also fixes some other problems. 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): 42990 - iptables-save: -c option causing problems as of 1.2.2-1.i386 50500 - iptables-save saves --reject-with icmp-host-prohibited as --reject-with tcp-reset 53325 - Errata conversion of iptables .... -m limit ##/sec 54280 - string_to_number buglets 31133 - do not assume that nat, mangle tables exist 54160 - iptables-save and iptables-restore parse and produce quotes differently from each other 6.
