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.
