RHEL 2.1 : mailman (RHSA-2004:156)
Medium Nessus Plugin ID 12485
SynopsisThe remote Red Hat host is missing a security update.
DescriptionAn updated mailman package that closes a DoS vulnerability in mailman introduced by RHSA-2004:019 is now available.
Mailman is a mailing list manager.
On February 19 2004, Red Hat issued security erratum RHSA-2004:019 to correct a DoS (Denial of Service) vulnerability where an attacker could send a carefully-crafted message and cause mailman to crash.
Matthew Saltzman discovered a flaw in our original patch intended to correct this vulnerability. This flaw can cause mailman to crash if it receives an email destined for a list with an empty subject field. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2004-0182 to this issue.
Users of Mailman are advised to upgrade to these updated packages, which include an updated patch and are not vulnerable to this issue.
SolutionUpdate the affected mailman package.
