Pipermail in Mailman stores private mail messages with predictable filenames in a world-executable directory, which allows local users to read private mailing list archives.
Cross-site scripting vulnerability in Mailman email archiver before 2.08 allows attackers to obtain sensitive information or authentication credentials via a malicious link that is accessed by other web users.
Mailman 2.0.x before 2.0.6 allows remote attackers to gain access to list administrative pages when there is an empty site or list password, which is not properly handled during the call to the crypt function during authentication.
