Hi everyone,
phpBB Group announces the release of phpBB 2.0.17, the "no, we did not forget naming it last time" release. This release addresses several bugfixes and some low security issues as well as the recently seemingly wide-spread XSS issue (only affecting Internet Explorer).
Please have a look down this announcement for the code changes necessary to fix the XSS issue, we are again astounded about the energy people put into finding the smallest issue in phpBB 2.0.x, those must have a lot of time available. But on the other hand it is always increasing the products security since we do not introduce new features into the 2.0.x codebase.
With this announcement I want to give you some more information regarding phpBB's security. psoTFX (Paul S. Owen, Project Manager) initiated and brought forward the idea and concept of a complete security audit of the 2.0.x codebase. We introduced some top-notch security people, phpBB-Modders and very talented people from our teams to participate in this audit. We intend to implement the changes necessary - and also fixing the found issues, hopefully giving the now very aged codebase (it is still on a technical level from three years ago) a lift and bringing it up-to-date with security mechanisms and techniques which are common nowadays.
We also intend to open our private bugtracker system to the public for reporting 2.0.x bugs within the next days.
As with all new releases we urge you to update as soon as possible. You can of course find this download available on our downloads page. As per usual three packages are available to simplify your update.
Full Package
Contains entire phpBB2 source and English language package
Changed Files Only
Contains only those files changed from previous versions of phpBB. Please note this archive contains changed files for each previous release
Patch Files
Contains patch compatible patches from the previous versions of phpBB.
As always, our Code Changes Tutorial is available too for those with heavily modded boards.
It can be downloaded from this location.
Select whichever package is most suitable for you.
Please ensure you read the INSTALL and README documents in docs/ before proceeding with installation or updates!.

Well, i think, that phpBB developers are underestimating seriousness of this bug  |
