Previous versions allowed users to run searches that might result in long execution times and load on larger boards when using the fulltext native search engine. To combat this, further restrictions were introduced on search queries.

For Debian 8 Jessie, this problem has been fixed in version 3.0.12-5+deb8u3.

We recommend that you upgrade your phpbb3 packages.
