USN-2254-2: PHP updates
Ubuntu Security Notice USN-2254-2
25th June, 2014
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 14.04 LTS
- Ubuntu 13.10
An improvement was made for PHP FPM environments.
- php5 - HTML-embedded scripting language interpreter
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.
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)
