Ubuntu Security Notice USN-2254-2
June 25, 2014

php5 updates
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 14.04 LTS
- Ubuntu 13.10

Summary:

An improvement was made for PHP FPM environments.

Software Description:
- php5: HTML-embedded scripting language interpreter

Details:

USN-2254-1 fixed vulnerabilities in PHP. The fix for CVE-2014-0185
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)

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 14.04 LTS:
  php5-fpm                        5.5.9+dfsg-1ubuntu4.2

Ubuntu 13.10:
  php5-fpm                        5.5.3+dfsg-1ubuntu2.5

In general, a standard system update will make all the necessary changes.
