Aliet Santiesteban Sifontes has reported a vulnerability in Mailman, which potentially can be exploited by malicious people to cause a DoS (Denial of Service).
The vulnerability is caused due to "Scrubber.py" failing to handle the exception condition when Python fails to process an email file attachment that contains utf8 characters in its filename. This can potentially be exploited to cause the mailing list to stop working via a specially crafted email.
The vulnerability has been reported in version 2.1.5. Other versions may also be affected.
Solution: The vulnerability has been fixed in version 2.1.7rc1.
