CentOS Errata and Security Advisory CESA-2005:358
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
