further restricted the permissions on the PHP FastCGI Process Manager (FPM)
UNIX socket. This update grants socket access to the www-data user and
group so installations and documentation relying on the previous socket
permissions will continue to function.

Original advisory details:

 Christian Hoffmann discovered that the PHP FastCGI Process Manager (FPM)
 set incorrect permissions on the UNIX socket. A local attacker could use
 this issue to possibly elevate their privileges. This issue only affected
 Ubuntu 12.04 LTS, Ubuntu 13.10, and Ubuntu 14.04 LTS. (CVE-2014-0185)

 Francisco Alonso discovered that the PHP Fileinfo component incorrectly
 handled certain CDF documents. A remote attacker could use this issue to
 cause PHP to hang or crash, resulting in a denial of service.
 (CVE-2014-0237, CVE-2014-0238)

 Stefan Esser discovered that PHP incorrectly handled DNS TXT records. A
 remote attacker could use this issue to cause PHP to crash, resulting in a
 denial of service, or possibly execute arbitrary code. (CVE-2014-4049)");
