--------------------------------------------------------------------- Fedora Legacy Update Advisory
Synopsis: Updated sendmail packages fix security issue Advisory ID: FLSA:186277 Issue date: 2006-04-04 Product: Red Hat Linux, Fedora Core Keywords: Bugfix, Security CVE Names: CVE-2006-0058 --------------------------------------------------------------------- --------------------------------------------------------------------- 1. Topic: Updated sendmail packages that fix a security issue are now available. The sendmail package provides a widely used Mail Transport Agent (MTA). [Updated 4th April 2006] Red Hat Linux 7.3, Red Hat Linux 9, and Fedora Core 1 packages have been updated to correct numerous problems with the previously released updates. 2. Relevant releases/architectures: Red Hat Linux 7.3 - i386 Red Hat Linux 9 - i386 Fedora Core 1 - i386 Fedora Core 2 - i386 Fedora Core 3 - i386, x86_64 3. Problem description: A flaw in the handling of asynchronous signals was discovered in Sendmail. A remote attacker may be able to exploit a race condition to execute arbitrary code as root. The Common Vulnerabilities and Exposures project assigned the name CVE-2006-0058 to this issue. In order to correct this issue for RHL 7.3 users, it was necessary to upgrade the version of Sendmail from 8.11 as originally shipped to Sendmail 8.12.11 with the addition of the security patch supplied by Sendmail Inc. This erratum provides updated packages based on Sendmail 8.12 with a compatibility mode enabled as provided by Red Hat for RHEL 2.1. After updating to these packages, users should pay close attention to their sendmail logs to ensure that the upgrade completed sucessfully. In order to correct this issue for RHL 9 and FC1 users, it was necessary to upgrade the version of Sendmail from 8.12.8 and 8.12.10 respectively to 8.12.11 with the addition of the security patch supplied by Sendmail Inc. After updating to these packages, users should pay close attention to their sendmail logs to ensure that the upgrade completed sucessfully. For Fedora Core 3 users, the patch supplied by Sendmail Inc. applies cleanly to the latest sendmail package previously released for Fedora Core 3. Users of Sendmail should upgrade to this updated package, which contains a backported patch to correct this issue. Users updating to these packages are urged to review their sendmail.cf file after updating. 4. Solution: Before applying this update, make sure all previously released errata relevant to your system have been applied. 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.
