Ubuntu 5.04 / 5.10 / 6.06 LTS : mailman vulnerabilities (USN-345-1)
Medium Nessus Plugin ID 27924
SynopsisThe remote Ubuntu host is missing a security-related patch.
DescriptionSteve Alexander discovered that mailman did not properly handle attachments with special filenames. A remote user could exploit that to stop mail delivery until the server administrator manually cleaned these posts. (CVE-2006-2941)
Various cross-site scripting vulnerabilities have been reported by Barry Warsaw. By using specially crafted email addresses, names, and similar arbitrary user-defined strings, a remote attacker could exploit this to run web script code in the list administrator's web browser. (CVE-2006-3636)
URLs logged to the error log file are now checked for invalid characters. Before, specially crafted URLs could inject arbitrary messages into the log.
Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
SolutionUpdate the affected mailman package.
