Fedora Core 3: 2005-132 Critical Mailman File Access Risk

Mailman is software to help manage email discussion lists, much like

Majordomo and Smartmail. Unlike most similar products, Mailman gives

each mailing list a webpage, and allows users to subscribe,

unsubscribe, etc. over the Web. Even the list manager can administer

his or her list entirely from the Web. Mailman also integrates most

things people want to do with mailing lists, including archiving, mail

<-> news gateways, and so on.

Documentation can be found in: /usr/share/doc/mailman-2.1.5

There is a critical security flaw in Mailman 2.1.5 which will allow

attackers to read arbitrary files.

The extent of the vulnerability depends on what version of Apache

(httpd) you are running, and (possibly) how you have configured your

web server. It is believed the vulnerability is not available when

Mailman is paired with a version of Apache >= 2.0, however earlier

versions of Apache, e.g. version 1.3, will allow the exploit when

executing a Mailman CGI script. All versions of Fedora have shipped

with the later 2.0 version of Apache and thus if you are running a

Fedora release you are not likely to be vulnerable to the exploit

unless you have explicitly downgraded the version of your web

server. However, installing this version of mailman with a security

patch represents a prudent safeguard.

This issue has been assigned CVE number CAN-2005-0202.

The bug report associated with this is:

https://bugzilla.redhat.com/show_bug.cgi?id=147343

The errata associated with this for RHEL releases is:

For additional piece of mind, it is recommended that you regenerate

your list member passwords. Instructions on how to do this, and more

information about this vulnerability are available here:
