"This erratum fixes two relatively minor security issues which were
discovered in Exim in the last few weeks. The Common Vulnerabilities
and Exposures project (cve.mitre.org) has assigned the names
CVE-2005-0021 and CVE-2005-0022 to these, respectively.

1. The function host_aton() can overflow a buffer if it is presented
with an illegal IPv6 address that has more than 8 components.

2. The second report described a buffer overflow in the function
spa_base64_to_bits(), which is part of the code for SPA
authentication. This code originated in the Samba project. The
overflow can be exploited only if you are using SPA authentication.

Note that Tenable Network Security has extracted the preceding
description block directly from the Fedora security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."

"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.

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 CVE-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 CVE-2005-0021 to this issue.

Users of Exim are advised to update to these erratum packages which
contain backported patches to correct these issues."

2. The second report described a buffer overflow in the function
spa_base64_to_bits(), which is part of the code for SPA

overflow can be exploited only if you are using SPA authentication.

has attempted to automatically clean and format it as much as possible

    Buffer overflows have been found in the host_aton() function
    (CAN-2005-0021) as well as in the spa_base64_to_bits() function
    (CAN-2005-0022), which is part of the SPA authentication code.
  
Impact :

    A local attacker could trigger the buffer overflow in host_aton()
    by supplying an illegal IPv6 address with more than 8 components, using
    a command line option. The second vulnerability could be remotely
    exploited during SPA authentication, if it is enabled on the server.
    Both buffer overflows can potentially lead to the execution of
    arbitrary code.
  
Workaround :

    There is no known workaround at this time."
