This is a follow-up to DLA-1942-1.

There was some confusion about the correct
fix for CVE-2019-13776.

The correct announcement for this DLA should have been:

Package        : phpbb3
Version        : 3.0.12-5+deb8u4
CVE ID         : CVE-2019-13776 CVE-2019-16993

CVE-2019-16993

   In phpBB, includes/acp/acp_bbcodes.php had improper verification of a
   CSRF token on the BBCode page in the Administration Control Panel. An
   actual CSRF attack was possible if an attacker also managed to retrieve
   the session id of a reauthenticated administrator prior to targeting
   them.

CVE-2019-13776

   phpBB allowed the stealing of an Administration Control Panel session id
   by leveraging CSRF in the Remote Avatar feature. The CSRF Token Hijacking
   lead to stored XSS.

For Debian 8 "Jessie", these problems have been fixed in version
3.0.12-5+deb8u4.

We recommend that you upgrade your phpbb3 packages.
