--------------------------------------------------------------------- Fedora Legacy Update Advisory Synopsis: Updated ipsec-tools package fixes security issue Advisory ID: FLSA:190941 Issue date: 2006-06-06 Product: Fedora Core Keywords: Bugfix CVE Names: CVE-2005-3732 --------------------------------------------------------------------- --------------------------------------------------------------------- 1. Topic: An updated ipsec-tools package that fixes a bug in racoon is now available. The ipsec-tools package is used in conjunction with the IPsec functionality in the linux kernel and includes racoon, an IKEv1 keying daemon. 2. Relevant releases/architectures: Fedora Core 2 - i386 Fedora Core 3 - i386, x86_64 3. Problem description: A denial of service flaw was found in the ipsec-tools racoon daemon. If a victim's machine has racoon configured in a non-recommended insecure manner, it is possible for a remote attacker to crash the racoon daemon. (CVE-2005-3732) Users of ipsec-tools should upgrade to this updated package, which contains backported patches, and is not vulnerable 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 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.
