The remote Redhat Enterprise Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2013:1615 advisory.

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

    It was found that PHP did not properly handle file names with 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-2006-7243)

    A flaw was found in PHP's SSL client's hostname identity check when     handling certificates that contain hostnames with NULL bytes. If an     attacker was able to get a carefully crafted certificate signed by a     trusted Certificate Authority, the attacker could use the certificate to     conduct man-in-the-middle attacks to spoof SSL servers. (CVE-2013-4248)

    It was found that the PHP SOAP parser allowed the expansion of external XML     entities during SOAP message parsing. A remote attacker could possibly use     this flaw to read arbitrary files that are accessible to a PHP application     using a SOAP extension. (CVE-2013-1643)

    This update fixes the following bugs:

    * Previously, when the allow_call_time_pass_reference setting was disabled,     a virtual host on the Apache server could terminate with a segmentation     fault when attempting to process certain PHP content. This bug has been     fixed and virtual hosts no longer crash when allow_call_time_pass_reference     is off. (BZ#892158, BZ#910466)

    * Prior to this update, if an error occurred during the operation of the     fclose(), file_put_contents(), or copy() function, the function did not     report it. This could have led to data loss. With this update, the     aforementioned functions have been modified to properly report any errors.
    (BZ#947429)

    * The internal buffer for the SQLSTATE error code can store maximum of 5     characters. Previously, when certain calls exceeded this limit, a buffer     overflow occurred. With this update, messages longer than 5 characters are     automatically replaced with the default HY000 string, thus preventing the     overflow. (BZ#969110)

    In addition, this update adds the following enhancement:

    * This update adds the following rpm macros to the php package: %__php,     %php_inidir, %php_incldir. (BZ#953814)

    Users of php are advised to upgrade to these updated packages, which fix     these bugs and add this enhancement. After installing the updated packages,     the httpd daemon must be restarted for the update to take effect.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

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