=========================================================== Ubuntu Security Notice USN-345-1 September 13, 2006 mailman vulnerabilities CVE-2006-2941, CVE-2006-3636, CVE-2006-4624 =========================================================== A security issue affects the following Ubuntu releases: Ubuntu 5.04 Ubuntu 5.10 Ubuntu 6.06 LTS This advisory also applies to the corresponding versions of Kubuntu, Edubuntu, and Xubuntu. The problem can be corrected by upgrading your system to the following package versions: Ubuntu 5.04: mailman 2.1.5-7ubuntu0.3 Ubuntu 5.10: mailman 2.1.5-8ubuntu2.3 Ubuntu 6.06 LTS: mailman 2.1.5-9ubuntu4.1 In general, a standard system upgrade is sufficient to effect the necessary changes. Details follow: Steve 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. (CVE-2006-4624)
