CVE-2016-5773 (opens in a new tab)How to fix?
Upgrade Ubuntu:16.04 php7.0 to version 7.0.8-0ubuntu0.16.04.1 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.
php_zip.c in the zip extension in PHP before 5.5.37, 5.6.x before 5.6.23, and 7.x before 7.0.8 improperly interacts with the unserialize implementation and garbage collection, which allows remote attackers to execute arbitrary code or cause a denial of service (use-after-free and application crash) via crafted serialized data containing a ZipArchive object.
