RHSA-2005-358: exim |
||
Check for the version of the exim packages Detailed Explanation for this Vulnerability Assessment 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. 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 rights of the 'exim' user. The Common Vulnerabilities and Exposures project assigned the name CVE-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 Solution : http://rhn.redhat.com/errata/RHSA-2005-358.html Network Security Threat Level: High Networks Security ID: Vulnerability Assessment Copyright: This script is Copyright (C) 2005 Tenable Network Security |
