GLSA-200609-12 : Mailman: Multiple vulnerabilities
Medium Nessus Plugin ID 22429
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-200609-12 (Mailman: Multiple vulnerabilities)
Mailman fails to properly handle standards-breaking RFC 2231 formatted headers. Furthermore, Moritz Naumann discovered several XSS vulnerabilities and a log file injection.
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.
There is no known workaround at this time.
SolutionAll Mailman users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=net-mail/mailman-2.1.9_rc1'
