New! Plugin Severity Now Using CVSS v3

Synopsis

The remote Ubuntu host is missing a security-related patch.

Description

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.

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).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected php5-fpm package.
