Red Hat alert RHSA-2011:0153-01 (exim)
-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Moderate: exim security update Advisory ID: RHSA-2011:0153-01 Product: Red Hat Enterprise Linux Advisory URL: https://rhn.redhat.com/errata/RHSA-2011-0153.html Issue date: 2011-01-17 CVE Names: CVE-2010-4345 ===================================================================== 1. Summary: Updated exim packages that fix one security issue are now available for Red Hat Enterprise Linux 4 and 5. The Red Hat Security Response Team has rated this update as having moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section. 2. Relevant releases/architectures: Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x, x86_64 Red Hat Enterprise Linux AS version 4 - i386, ia64, ppc, s390, s390x, x86_64 Red Hat Enterprise Linux Desktop (v. 5 client) - i386, x86_64 Red Hat Enterprise Linux Desktop version 4 - i386, x86_64 Red Hat Enterprise Linux ES version 4 - i386, ia64, x86_64 Red Hat Enterprise Linux WS version 4 - i386, ia64, x86_64 3. Description: Exim is a mail transport agent (MTA) developed at the University of Cambridge for use on UNIX systems connected to the Internet. A privilege escalation flaw was discovered in Exim. If an attacker were able to gain access to the "exim" user, they could cause Exim to execute arbitrary commands as the root user. (CVE-2010-4345) This update adds a new configuration file, "/etc/exim/trusted-configs". To prevent Exim from running arbitrary commands as root, Exim will now drop privileges when run with a configuration file not listed as trusted. This could break backwards compatibility with some Exim configurations, as the trusted-configs file only trusts "/etc/exim/exim.conf" and "/etc/exim/exim4.conf" by default. If you are using a configuration file not listed in the new trusted-configs file, you will need to add it manually. Additionally, Exim will no longer allow a user to execute exim as root with the -D command line option to override macro definitions. All macro definitions that require root permissions must now reside in a trusted configuration file. Users of Exim are advised to upgrade to these updated packages, which contain a backported patch to correct this issue. After installing this update, the exim daemon will be restarted automatically. 4. Solution: Before applying this update, make sure all previously-released errata relevant to your system have been applied. This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at http://kbase.redhat.com/faq/docs/DOC-11259 5.
