CVE-2006-0052

Description:
Two vulnerabilities have been reported in Mailman, which can be exploited by malicious people to disclose sensitive information or cause a DoS (Denial of Service).
1) An input validation error in private.py makes it possible to disclose the contents of arbitrary files via directory traversal attacks via the ".../....///" sequence.
Successful exploitation may reportedly depend on the installed Apache version and its configuration. Mailman installed on Apache 2.x versions is not believed to be affected.
2) An error when processing multipart messages can be exploited to prevent new messages sent to a list from being processed by sending a specially crafted multipart message to the list.
The vulnerabilities have been reported in version 2.1.5. Prior versions may also be affected.
Solution:
Update to version 2.1.6 or later.
Provided and/or discovered by:
1) John Cartwright
2) Duncan Salada
