Mandriva Linux Security Advisory MDKSA-2006:165
http://www.mandriva.com/security/
_______________________________________________________________________

Package : mailman
Date : September 18, 2006
Affected: 2006.0, Corporate 3.0
_______________________________________________________________________

Problem Description:

A flaw was discovered in how Mailman handles MIME multipart messages
where an attacker could send a carefully-crafted MIME multipart
message to a Mailman-run mailing list causing that mailing list to
stop working (CVE-2006-2941).

As well, a number of XSS (cross-site scripting) issues were discovered
that could be exploited to perform XSS attacks against the Mailman
administrator (CVE-2006-3636).

Finally, a CRLF injection vulnerability allows remote attackers to
spoof messages in the error log (CVE-2006-4624).

Updated packages have been patched to address these issues.
