CVE-2016-5773

Priority
Description
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.
Notes
mdeslaurApplications should never deserialize unauthenticated data.
precise needs backported fix
we will not be fixing this in Ubuntu 12.04 LTS. We recommend
validating untrusted data before unserializing.
