    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
    EnableViewStateMac property. If a user were tricked into opening a
    specially crafted URL, an attacker could possibly exploit this to conduct
    cross-site scripting (XSS) attacks. This issue only affected Ubuntu
    10.04 LTS. (CVE-2010-1459)

      libmono-system-web4.0-cil       2.10.8.1-1ubuntu2.2
    
    Ubuntu 11.10:
      libmono-system-web2.0-cil       2.10.5-1ubuntu0.1
      libmono-system-web4.0-cil       2.10.5-1ubuntu0.1
