Synopsis: Moderate: exim security update Advisory ID: RHSA-2005:358-01 Advisory URL: https://rhn.redhat.com/errata/RHSA-2005-358.html Issue date: 2005-09-08 Updated on: 2005-09-08 Product: Red Hat Enterprise Linux Cross references: RHSA-2005:761 CVE Names: CAN-2005-2491 - ---------------------------------------------------------------------
1. Summary:
Updated exim packages that fix a security issue in PCRE and a free space computation on large file system bug are now available for Red Hat Enterprise Linux 4.
This update has been rated as having moderate security impact by the Red Hat Security Response Team.
2. Relevant releases/architectures:
Red Hat Enterprise Linux AS version 4 - i386, ia64, ppc, s390, s390x, 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. Problem description:
Exim is a mail transport agent (MTA) developed at the University of Cambridge for use on Unix systems connected to the Internet.
An integer overflow flaw was found in PCRE, a Perl-compatible regular expression library included within Exim. A local user could create a maliciously crafted regular expression in such as way that they could gain the privileges of the 'exim' user. The Common Vulnerabilities and Exposures project assigned the name CAN-2005-2491 to this issue. These erratum packages change Exim to use the system PCRE library instead of the internal one.
These packages also fix a minor flaw where the Exim Monitor was incorrectly computing free space on very large file systems.
Users should upgrade to these erratum packages and also ensure they have updated the system PCRE library, for which erratum packages are available seperately in RHSA-2005:761
4. Solution:
Before applying this update, make sure that all previously-released errata relevant to your system have been applied. Use Red Hat Network to download and update your packages. To launch the Red Hat Update Agent, use the following command:
up2date
For information on how to install packages manually, refer to the following Web page for the System Administration or Customization guide specific to your system:
