==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

Summary:

Mono could be made to expose sensitive information over the network.

Software Description:
- mono: Mono is a platform for running and developing applications

Details:

It was discovered that the Mono System.Web library incorrectly filtered
certain error messages related to forbidden files. If a user were tricked
into opening a specially crafted URL, an attacker could possibly exploit
this to conduct cross-site scripting (XSS) attacks. (CVE-2012-3382)

It was discovered that the Mono System.Web library incorrectly handled the

specially crafted URL, an attacker could possibly exploit this to conduct
cross-site scripting (XSS) attacks. This issue only affected Ubuntu
