The mod_pagespeed team would like to let you know of an important security update, version 0.10.22.6.  Please see immediately below for details (the release does not introduce any new functionality, but behavior in complex setups may be slightly changed).

If you installed the .rpm package, you can update with:
sudo yum update mod-pagespeed-beta
sudo /etc/init.d/httpd restart

If you installed the .deb package, you can update with:
sudo apt-get update
sudo apt-get upgrade

mod_pagespeed 0.10.22.6 Security Update.

Overview

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.

Hi Carl, great to hear from you.  Let's see if we can sort this out.  What are "kbF" and "Hits" as opposed to the other stats?

In your installation, do you configure your virtual hosts with explicit ServerName?

This update adversely affected the Webmin stats - specifically the "kbF" and "Hits" values. The Visits and Sites values are unaffected, making the Webmin graph look really weird - we've the same visits and sites per day for the week, so that graph line is normal, but from 3 days ago there appears to have been no data served!  I've deleted the entire cache and even rebooted the server, with no effect. Site performance is unaffected, and the browser header shows X-Mod-Pagespeed: 0.10.22.6-1798.

In several years of running mod_pagespeed normally, this is the first time I've seen this. In fact the excellent performance is what's kept me largely as a mere lurker here until this ;-)
