mod_pagespeed -- multiple vulnerabilities

Google Reports:

mod_pagespeed 0.10.22.6 is a security update that fixes two
critical issues that affect earlier versions:

CVE-2012-4001, a problem with validation of own host name.
CVE-2012-4360, a cross-site scripting attack, which affects versions starting from 0.10.19.1.

The effect of the first problem is that it is possible to confuse
mod_pagespeed about its own host name, and to trick it into
fetching resources from other machines. This could be an issue if
the HTTP server has access to machines that are not otherwise
publicly visible.
The second problem would permit a hostile third party to execute
JavaScript in users’ browsers in context of the domain running
mod_pagespeed, which could permit interception of users’ cookies or
data on the site.
Because of the severity of the two problems, users are strongly
encouraged to update immediately.
Behavior Changes in the Update:
As part of the fix to the first issue, mod_pagespeed will not fetch
resources from machines other than localhost if they are not
explicitly mentioned in the configuration. This means that if you
need resources on the server’s domain to be handled by some other
system, you’ll need to explicitly use ModPagespeedMapOriginDomain
or ModPagespeedDomain to authorize that.
