From marcdeslauriers@videotron.ca Thu Feb 10 18:29:13 2005 From: Marc Deslauriers To: bugtraq@securityfocus.com, full-disclosure@lists.netsys.com Date: Thu, 10 Feb 2005 18:03:06 -0500 Subject: [Full-Disclosure] [FLSA-2005:2252] Updated iptables packages resolve security issues --------------------------------------------------------------------- Fedora Legacy Update Advisory Synopsis: Updated iptables packages resolve security issues Advisory ID: FLSA:2252 Issue date: 2005-02-10 Product: Red Hat Linux, Fedora Core Keywords: Bugfix Cross references: https://bugzilla.fedora.us/show_bug.cgi?id=2252 CVE Names: CAN-2004-0986 --------------------------------------------------------------------- --------------------------------------------------------------------- 1. Topic: Updated iptables packages that correct a security problem are now available. The iptables utility controls the network packet filtering code in the Linux kernel. 2. Relevant releases/architectures: Red Hat Linux 7.3 - i386 Red Hat Linux 9 - i386 Fedora Core 1 - i386 3. Problem description: Under certain conditions, iptables did not properly load the required modules at system startup, which caused the firewall rules to fail to load and protect the system from remote attackers. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0986 to this issue. Users of iptables are advised to upgrade to these errata packages, which contain backported patches correcting these issues. 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 yum and apt. Many people find this an easier way to apply updates. To use yum issue: yum update or to use apt: apt-get update; apt-get upgrade This will start an interactive process that will result in the appropriate RPMs being upgraded on your system. This assumes that you have yum or apt-get configured for obtaining Fedora Legacy content. Please visit http://www fedoralegacy.org/docs for directions on how to configure yum and apt-get. 5.
