CVE-2016-7125 (opens in a new tab)How to fix?
Upgrade Ubuntu:16.04 php7.0 to version 7.0.8-0ubuntu0.16.04.3 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream php7.0 package and not the php7.0 package as distributed by Ubuntu.
See How to fix? for Ubuntu:16.04 relevant fixed versions and status.
ext/session/session.c in PHP before 5.6.25 and 7.x before 7.0.10 skips invalid session names in a way that triggers incorrect parsing, which allows remote attackers to inject arbitrary-type session data by leveraging control of a session name, as demonstrated by object injection.
