- --------------------------BEGIN INCLUDED TEXT--------------------
Package : phpbb3
Version : 3.0.12-5+deb8u3
CVE ID : CVE-2019-9826
Colin Snover discovered a denial-of-service vulnerability in phpBB3, a
full-featured web forum. 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
We recommend that you upgrade your phpbb3 packages.
