(CVE-2009-0217)

It was discovered that Mono did not properly escape certain attributes in
the ASP.net class libraries which could result in browsers becoming
vulnerable to cross-site scripting attacks when processing the output. 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 (such as
passwords), within the same domain. This issue only affected Ubuntu 8.04
LTS. (CVE-2008-3422)

It was discovered that Mono did not properly filter CRLF injections in the
query string. If a user were tricked into viewing server output during a
crafted server request, a remote attacker could exploit this to modify the
contents, steal confidential data (such as passwords), or perform
cross-site request forgeries. This issue only affected Ubuntu 8.04 LTS.
