Red Hat alert RHSA-2005:025-01 (exim)
-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - --------------------------------------------------------------------- Red Hat Security Advisory Synopsis: Moderate: exim security update Advisory ID: RHSA-2005:025-01 Advisory URL: https://rhn.redhat.com/errata/RHSA-2005-025.html Issue date: 2005-02-15 Updated on: 2005-02-15 Product: Red Hat Enterprise Linux CVE Names: CAN-2005-0021 CAN-2005-0022 - --------------------------------------------------------------------- 1. Summary: Updated exim packages that resolve security issues 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. A buffer overflow was discovered in the spa_base64_to_bits function in Exim, as originally obtained from Samba code. If SPA authentication is enabled, a remote attacker may be able to exploit this vulnerability to execute arbitrary code as the 'exim' user. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2005-0022 to this issue. Please note that SPA authentication is not enabled by default in Red Hat Enterprise Linux 4. Buffer overflow flaws were discovered in the host_aton and dns_build_reverse functions in Exim. A local user can trigger these flaws by executing exim with carefully crafted command line arguments and may be able to gain the privileges of the 'exim' account. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2005-0021 to this issue. Users of Exim are advised to update to these erratum packages which contain backported patches to correct these issues. 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: http://www.redhat.com/docs/manuals/enterprise/ 5.
