According to its banner, the version of PHP running on the remote web server is 5.6.x prior to 5.6.18. It is, therefore, affected by multiple vulnerabilities :

  - The Perl-Compatible Regular Expressions (PCRE) library     is affected by multiple vulnerabilities related to the     handling of regular expressions, subroutine calls, and     binary files. A remote attacker can exploit these to     cause a denial of service, obtain sensitive information,     or have other unspecified impact. (CVE-2015-8383,     CVE-2015-8386, CVE-2015-8387, CVE-2015-8389,     CVE-2015-8390, CVE-2015-8391, CVE-2015-8393,     CVE-2015-8394)

  - A flaw exists in file ext/standard/exec.c in the     escapeshellcmd() and escapeshellarg() functions due to     the program truncating NULL bytes in strings. A remote     attacker can exploit this to bypass restrictions.

  - A flaw exists in file ext/standard/streamsfuncs.c in the     stream_get_meta_data() function due to a failure to     restrict writing user-supplied data to fields not     already set. A remote attacker can exploit this to     falsify the output of the function, resulting in the     insertion of malicious metadata.

  - A type confusion error exists in file ext/wddx/wddx.c in     the php_wddx_pop_element() function when deserializing     WDDX packets. A remote attacker can exploit this to have     an unspecified impact.

  - A flaw exists in file ext/phar/phar_object.c in the     PharFileInfo::getContent() method due to the use of     uninitialized memory causing improper validation of     user-supplied input. A remote attacker can exploit this     to corrupt memory, resulting in a denial of service or     the execution of arbitrary code.

  - A NULL pointer dereference flaw exists in file     ext/phar/tar.c in the phar_tar_setupmetadata() function     when parsing metadata from a crafted TAR file. A remote     attacker can exploit this to cause a denial of service.

  - An integer overflow condition exists in file     ext/standard/iptc.c in the iptcembed() function due to     improper validation of user-supplied input. A remote     attacker can exploit this to cause a heap-based buffer     overflow, resulting in a denial of service or the     execution of arbitrary code.

  - An overflow condition exists in file ext/phar/tar.c in     the phar_parse_tarfile() function due to improper     validation of user-supplied input when decompressing     TAR files. A remote attacker can exploit this to cause     a stack-based buffer overflow, resulting in a denial of     service or the execution of arbitrary code.

Update to 8.38 and fix various CVE's

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

The remote host is affected by the vulnerability described in GLSA-201607-02 (libpcre: Multiple Vulnerabilities)

    Multiple vulnerabilities have been discovered in libpcre. Please review       the CVE identifiers referenced below for details.
  Impact :

    An attacker can possibly execute arbitrary code or create a Denial of       Service condition.
  Workaround :

    There is no known workaround at this time.

The Tenable SecurityCenter application installed on the remote host is either prior to version 5.3.0 or is missing a security patch. It is, therefore, affected by multiple vulnerabilities in the Perl-Compatible Regular Expressions (PCRE) library bundled with PHP :

  - An overflow condition exists in the PCRE library due to     improper validation of user-supplied input when handling     repeated conditional groups. An attacker can exploit     this, via a specially crafted regular expression, to     cause a buffer overflow, resulting in a denial of     service condition. (CVE-2015-8383)

  - An overflow condition exists in the PCRE library due to     improper validation of user-supplied input when handling     mutual recursions within a 'lookbehind' assertion. An     attacker can exploit this to cause a stack-based buffer     overflow, resulting in a denial of service condition.
    (CVE-2015-8386)

  - An integer overflow condition exists in the PCRE library     due to improper validation of user-supplied input when     handling subroutine calls. An attacker can exploit this,     via a specially crafted regular expression, to cause a     denial of service condition. (CVE-2015-8387)

  - A flaw exists in the PCRE library due to improper     handling of the /(?:|a|){100}x/ pattern or other related     patterns. An attacker can exploit this, via a specially     crafted regular expression, to cause an infinite     recursion, resulting in a denial of service condition.
    (CVE-2015-8389)

  - A flaw exists in the PCRE library due to improper     handling of the [: and \\ substrings in character     classes. An attacker can exploit this, via a specially     crafted regular expression, to cause an uninitialized     memory read, resulting in a denial of service condition.
    (CVE-2015-8390)

  - A flaw exists in the PCRE library in the pcre_compile()     function in pcre_compile.c due to improper handling of     [: nesting. An attacker can exploit this, via a     specially crafted regular expression, to cause an     excessive consumption of CPU resources, resulting in a     denial of service condition. (CVE-2015-8391)

  - A flaw exists in the PCRE library due to improper     handling of the '-q' option for binary files. An     attacker can exploit this, via a specially crafted file,     to disclose sensitive information. (CVE-2015-8393)

  - An integer overflow condition exists in the PCRE library     due to improper validation of user-supplied input when     handling the (?(<digits>) and (?(R<digits>) conditions.
    An attacker can exploit this, via a specially crafted     regular expression, to cause a denial of service     condition. (CVE-2015-8394)

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

This release fixes these vulnerabilies: CVE-2015-8383, CVE-2015-8386, CVE-2015-8387, CVE-2015-8389, CVE-2015-8390, CVE-2015-8391, CVE-2015-8393, CVE-2015-8394. It also fixes compiling comments with auto-callouts, compiling expressions with negated classes in UCP mode, compiling expressions with an isolated \E between an item and its qualifier with auto-callouts, a crash in regexec() if REG_STARTEND option is set and pmatch argument is NULL, a stack overflow when formatting a 32-bit integer in pcregrep tool, compiling expressions with an empty \Q\E sequence between an item and its qualifier with auto-callouts, compiling expressions with global extended modifier that is disabled by local no-extended option at the start of the expression just after a whitespace, a possible crash in pcre_copy_named_substring() if a named substring has number greater than the space in the ovector, a buffer overflow when compiling an expression with named groups with a group that reset capture numbers, and a crash in pcre_get_substring_list() if the use of \K caused the start of the match to be earlier than the end.
