[Cc:ing security@ as Sarge is affected as well]

phpbb 2.0.16 fixes a security issue due to inproper escaping of the
$highlight_match variable in viewtopic.php.

Upstream developers classify it as critical and provide something that
has a close resemblance of a patch:

This hole was introduced in a post-sarge version, and we didn't copy
this bug back while backporting fixes -- the error was a half escaping
of backslashes causing malicious code to be able to be executed.

So: Debian is not vulnerable.
