=========================================================== Ubuntu Security Notice USN-586-1 March 15, 2008 mailman vulnerability CVE-2008-0564 =========================================================== A security issue affects the following Ubuntu releases: Ubuntu 6.06 LTS Ubuntu 6.10 Ubuntu 7.04 Ubuntu 7.10 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 6.06 LTS: mailman 2.1.5-9ubuntu4.2 Ubuntu 6.10: mailman 1:2.1.8-2ubuntu2.1 Ubuntu 7.04: mailman 1:2.1.9-4ubuntu1.2 Ubuntu 7.10: mailman 1:2.1.9-8ubuntu0.2 In general, a standard system upgrade is sufficient to effect the necessary changes. NOTE: Due to an internal release testing mistake, earlier published mailman versions 1:2.1.9-4ubuntu1.1 (for Ubuntu 7.04) and 1:2.1.9-8ubuntu0.1 (for Ubuntu 7.10) accidentally included an incorrect patch and caused a regression, as reported in https://launchpad.net/bugs/202332 This update includes fixes for the problem. We apologize for the inconvenience. Details follow: Multiple cross-site scripting flaws were discovered in mailman. A malicious list administrator could exploit this to execute arbitrary JavaScript, potentially stealing user credentials.
