Severity:	normal
Title:	Mailman: Multiple vulnerabilities
Date:	09/19/2006
Bugs:	#139976
ID:	200609-12

Synopsis

Mailman has multiple vulnerable that can result in Denial of Service, log file injection and XSS.

Background

Mailman is a Python based mailing list server with an extensive web interface.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
net-mail/mailman	< 2.1.9_rc1	>= 2.1.9_rc1	All supported architectures

Description

Mailman fails to properly handle standards-breaking RFC 2231 formatted headers. Furthermore, Moritz Naumann discovered several XSS vulnerabilities and a log file injection.

Impact

An attacker could exploit these vulnerabilities to cause Mailman to stop processing mails, to inject content into the log file or to execute arbitrary scripts running in the context of the administrator or mailing list user's browser.

Workaround

There is no known workaround at this time.

Resolution

All Mailman users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=net-mail/mailman-2.1.9_rc1"
