(RHSA-2004:019) mailman security update

Mailman is a mailing list manager.

Matthew Galgoci of Red Hat discovered a Denial of Service (DoS)
vulnerability in versions of Mailman prior to 2.1. An attacker could send
a carefully-crafted message causing mailman to crash. The Common
Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name
CAN-2003-0991 to this issue.

Users of Mailman are advised to upgrade to the erratum packages, which
include a backported security fix and are not vulnerable to this issue.

Red Hat would like to thank Barry Warsaw for providing a patch for this issue.
