PHP 5.5.x < 5.5.22 Multiple Vulnerabilities (GHOST)

critical Nessus Plugin ID 81511

Language:

Synopsis

The remote web server uses a version of PHP that is affected by multiple vulnerabilities.

Description

According to its banner, the version of PHP 5.5.x installed on the remote host is prior to 5.5.22. It is, therefore, affected by multiple vulnerabilities :

- A heap-based buffer overflow flaw in the enchant_broker_request_dict function in ext/enchant/enchant.c could allow a remote attacker to cause a buffer overflow, resulting in a denial of service condition or the execution of arbitrary code. (CVE-2014-9705)

- A heap-based buffer overflow flaw in the GNU C Library (glibc) due to improperly validating user-supplied input in the glibc functions __nss_hostname_digits_dots(), gethostbyname(), and gethostbyname2(). This allows a remote attacker to cause a buffer overflow, resulting in a denial of service condition or the execution of arbitrary code. (CVE-2015-0235)

- A use-after-free flaw exists in the function php_date_timezone_initialize_from_hash() within the 'ext/date/php_date.c' script. An attacker can exploit this to access sensitive information or crash applications linked to PHP. (CVE-2015-0273)

- A use-after-free vulnerability in the phar_rename_archive function in phar_object.c could allow a remote attacker to cause a denial of service.
(CVE-2015-2301)

- An XML External Entity (XXE) flaw exists in the PHP-FPM component due to improper parsing of XML data. A remote attacker can exploit this, via specially crafted XML data, to disclose sensitive information or cause a denial of service. (CVE-2015-8866) Note that Nessus has not attempted to exploit these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade to PHP version 5.5.22 or later.
