11 May 2009
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 9.04

It was discovered that MoinMoin did not properly sanitize its input when attaching files, resulting in cross-site scripting (XSS) vulnerabilities. With cross-site scripting vulnerabilities, if a user were tricked into viewing server output during a crafted server request, a remote attacker could exploit this to modify the contents, or steal confidential data, within the same domain.
The problem can be corrected by updating your system to the following package versions:
To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.
