An updated mailman package that fixes two security issues is now available
for Red Hat Enterprise Linux 3 and 4.
This update has been rated as having moderate security impact by the Red
Hat Security Response Team.
Mailman is software to help manage email discussion lists.
A flaw in handling of UTF8 character encodings was found in Mailman. An
attacker could send a carefully crafted email message to a mailing list run
by Mailman which would cause that particular mailing list to stop working.
The Common Vulnerabilities and Exposures project assigned the name
CVE-2005-3573 to this issue.
A flaw in date handling was found in Mailman version 2.1.4 through 2.1.6.
An attacker could send a carefully crafted email message to a mailing list
run by Mailman which would cause the Mailman server to crash. (CVE-2005-4153).
Users of Mailman should upgrade to this updated package, which contains
backported patches to correct these issues.
