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.
