According to its banner, the version of PHP 5.5.x installed on the remote host is prior to 5.5.21. It is, therefore, affected by multiple vulnerabilities:

  - A double free vulnerability in the     zend_ts_hash_graceful_destroy function in     zend_ts_hash.c in the Zend Engine could allow a remote     attacker to cause a denial of service. (CVE-2014-9425)

  - An out-of-bounds read flaw in file 'cgi_main.c' exists     when nmap is used to process an invalid file that begins     with a hash character (#) but lacks a newline character.
    A remote attacker, using a specially crafted PHP file,     can exploit this vulnerability to disclose memory     contents, cause a denial of service, or possibly execute     code. (CVE-2014-9427)

  - The mconvert function in softmagic.c does not properly     handle a certain string-length field during a copy of a     truncated version of a Pascal string, which could allow     a remote attacker to cause a denial of service.
    (CVE-2014-9652)

  - An out-of-bounds read issue exists in the GetCode_()     function in 'gd_gif_in.c'. This allows a remote attacker     to disclose memory contents. (CVE-2014-9709)

  - A use-after-free memory error exists in the     process_nested_data() function in 'var_unserializer.re'     due to improper handling of duplicate numerical keys     within the serialized properties of an object. A remote     attacker, using a crafted unserialize method call, can     exploit this vulnerability to execute arbitrary code.
    (CVE-2015-0231)

  - A flaw exists in the exif_process_unicode() function in     'exif.c' that allows freeing an uninitialized pointer. A     remote attacker, using specially crafted EXIF data in a     JPEG image, can exploit this to cause a denial of     service or to execute arbitrary code. (CVE-2015-0232)

Note that Nessus has not attempted to exploit these issues but has instead relied only on the application's self-reported version number.

Updated php packages that fix multiple security issues and several bugs are now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having Important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

PHP is an HTML-embedded scripting language commonly used with the Apache HTTP Server.

A flaw was found in the way the PHP module for the Apache httpd web server handled pipelined requests. A remote attacker could use this flaw to trigger the execution of a PHP script in a deinitialized interpreter, causing it to crash or, possibly, execute arbitrary code.
(CVE-2015-3330)

A flaw was found in the way PHP parsed multipart HTTP POST requests. A specially crafted request could cause PHP to use an excessive amount of CPU time. (CVE-2015-4024)

An uninitialized pointer use flaw was found in PHP's Exif extension. A specially crafted JPEG or TIFF file could cause a PHP application using the exif_read_data() function to crash or, possibly, execute arbitrary code with the privileges of the user running that PHP application. (CVE-2015-0232)

An integer overflow flaw leading to a heap-based buffer overflow was found in the way PHP's FTP extension parsed file listing FTP server responses. A malicious FTP server could use this flaw to cause a PHP application to crash or, possibly, execute arbitrary code.
(CVE-2015-4022)

Multiple flaws were discovered in the way PHP performed object unserialization. Specially crafted input processed by the unserialize() function could cause a PHP application to crash or, possibly, execute arbitrary code. (CVE-2014-8142, CVE-2015-0231, CVE-2015-0273, CVE-2015-2787, CVE-2015-4147, CVE-2015-4148, CVE-2015-4599, CVE-2015-4600, CVE-2015-4601, CVE-2015-4602, CVE-2015-4603)

It was found that certain PHP functions did not properly handle file names containing a NULL character. A remote attacker could possibly use this flaw to make a PHP script access unexpected files and bypass intended file system access restrictions. (CVE-2015-2348, CVE-2015-4025, CVE-2015-4026, CVE-2015-3411, CVE-2015-3412, CVE-2015-4598)

Multiple flaws were found in the way the way PHP's Phar extension parsed Phar archives. A specially crafted archive could cause PHP to crash or, possibly, execute arbitrary code when opened.
(CVE-2015-2301, CVE-2015-2783, CVE-2015-3307, CVE-2015-3329, CVE-2015-4021)

Multiple flaws were found in PHP's File Information (fileinfo) extension. A remote attacker could cause a PHP application to crash if it used fileinfo to identify type of attacker supplied files.
(CVE-2014-9652, CVE-2015-4604, CVE-2015-4605)

A heap buffer overflow flaw was found in the enchant_broker_request_dict() function of PHP's enchant extension. An attacker able to make a PHP application enchant dictionaries could possibly cause it to crash. (CVE-2014-9705)

A buffer over-read flaw was found in the GD library used by the PHP gd extension. A specially crafted GIF file could cause a PHP application using the imagecreatefromgif() function to crash. (CVE-2014-9709)

This update also fixes the following bugs :

* The libgmp library in some cases terminated unexpectedly with a segmentation fault when being used with other libraries that use the GMP memory management. With this update, PHP no longer changes libgmp memory allocators, which prevents the described crash from occurring.
(BZ#1212305)

* When using the Open Database Connectivity (ODBC) API, the PHP process in some cases terminated unexpectedly with a segmentation fault. The underlying code has been adjusted to prevent this crash.
(BZ#1212299)

* Previously, running PHP on a big-endian system sometimes led to memory corruption in the fileinfo module. This update adjusts the behavior of the PHP pointer so that it can be freed without causing memory corruption. (BZ#1212298)

All php users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. After installing the updated packages, the httpd daemon must be restarted for the update to take effect.

The file command is used to identify a particular file according to the type of data the file contains. It can identify many different file types, including Executable and Linkable Format (ELF) binary files, system libraries, RPM packages, and different graphics formats.

Multiple denial of service flaws were found in the way file parsed certain Composite Document Format (CDF) files. A remote attacker could use either of these flaws to crash file, or an application using file, via a specially crafted CDF file. (CVE-2014-0207, CVE-2014-0237, CVE-2014-0238, CVE-2014-3479, CVE-2014-3480, CVE-2014-3487, CVE-2014-3587)

Two flaws were found in the way file processed certain Pascal strings.
A remote attacker could cause file to crash if it was used to identify the type of the attacker-supplied file. (CVE-2014-3478, CVE-2014-9652)

Multiple flaws were found in the file regular expression rules for detecting various files. A remote attacker could use these flaws to cause file to consume an excessive amount of CPU. (CVE-2014-3538)

Multiple flaws were found in the way file parsed Executable and Linkable Format (ELF) files. A remote attacker could use these flaws to cause file to crash, disclose portions of its memory, or consume an excessive amount of system resources. (CVE-2014-3710, CVE-2014-8116, CVE-2014-8117, CVE-2014-9653)
