the USN-2254-1 advisory.

    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)
