According to its banner, the version of PHP running on the remote web server is 5.5.x prior to 5.5.34. It is, therefore, affected by multiple vulnerabilities :

  - A buffer over-write condition exists in the finfo_open()     function due to improper validation of magic files. An     unauthenticated, remote attacker can exploit this, via a     crafted file, to cause a denial of service or to execute     arbitrary code. (CVE-2015-8865)

  - An integer overflow condition exists in the     php_raw_url_encode() function within file     ext/standard/url.c due to improper validation of     user-supplied input. An unauthenticated, remote attacker     can exploit this to have an unspecified impact.
    (CVE-2016-4070)     
  - A flaw exists in the php_snmp_error() function within     file ext/snmp/snmp.c that is triggered when handling     format string specifiers. An unauthenticated, remote     attacker can exploit this, via a crafted SNMP object,     to cause a denial of service or to execute arbitrary     code. (CVE-2016-4071)

  - An invalid memory write error exists when handling     the path of phar file names that allows an attacker     to have an unspecified impact. (CVE-2016-4072)

  - A flaw exists in the mbfl_strcut() function within file     ext/mbstring/libmbfl/mbfl/mbfilter.c when handling     negative parameter values. An unauthenticated, remote     attacker can exploit this to cause a denial of service.
    (CVE-2016-4073)

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

Several vulnerabilities were found in PHP, a general-purpose scripting language commonly used for web application development.

The vulnerabilities are addressed by upgrading PHP to the new upstream version 5.6.20, which includes additional bug fixes. Please refer to the upstream changelog for more information :

  - https://php.net/ChangeLog-5.php#5.6.20

- CVE-2015-8865 The file_check_mem function in funcs.c in     file before 5.23, as used in the Fileinfo component in     PHP before 5.5.34, 5.6.x before 5.6.20, and 7.x before     7.0.5, mishandles continuation-level jumps, which allows     context-dependent attackers to cause a denial of service     (buffer overflow and application crash) or possibly     execute arbitrary code via a crafted magic file.

  - CVE-2015-8866 libxml_disable_entity_loader setting is     shared between threads ext/libxml/libxml.c in PHP before     5.5.22 and 5.6.x before 5.6.6, when PHP-FPM is used,     does not isolate each thread from     libxml_disable_entity_loader changes in other threads,     which allows remote attackers to conduct XML External     Entity (XXE) and XML Entity Expansion (XEE) attacks via     a crafted XML document, a related issue to     CVE-2015-5161.

  - CVE-2015-8878 main/php_open_temporary_file.c in PHP     before 5.5.28 and 5.6.x before 5.6.12 does not ensure     thread safety, which allows remote attackers to cause a     denial of service (race condition and heap memory     corruption) by leveraging an application that performs     many temporary-file accesses.

  - CVE-2015-8879 The odbc_bindcols function in     ext/odbc/php_odbc.c in PHP before 5.6.12 mishandles     driver behavior for SQL_WVARCHAR columns, which allows     remote attackers to cause a denial of service     (application crash) in opportunistic circumstances by     leveraging use of the odbc_fetch_array function to     access a certain type of Microsoft SQL Server table.

  - CVE-2016-4070 Integer overflow in the php_raw_url_encode     function in ext/standard/url.c in PHP before 5.5.34,     5.6.x before 5.6.20, and 7.x before 7.0.5 allows remote     attackers to cause a denial of service (application     crash) via a long string to the rawurlencode function.

  - CVE-2016-4071 Format string vulnerability in the     php_snmp_error function in ext/snmp/snmp.c in PHP before     5.5.34, 5.6.x before 5.6.20, and 7.x before 7.0.5 allows     remote attackers to execute arbitrary code via format     string specifiers in an SNMP::get call.

  - CVE-2016-4072 The Phar extension in PHP before 5.5.34,     5.6.x before 5.6.20, and 7.x before 7.0.5 allows remote     attackers to execute arbitrary code via a crafted     filename, as demonstrated by mishandling of \0     characters by the phar_analyze_path function in     ext/phar/phar.c.

  - CVE-2016-4073 Multiple integer overflows in the     mbfl_strcut function in     ext/mbstring/libmbfl/mbfl/mbfilter.c in PHP before     5.5.34, 5.6.x before 5.6.20, and 7.x before 7.0.5 allow     remote attackers to cause a denial of service     (application crash) or possibly execute arbitrary code     via a crafted mb_strcut call.

  - CVE-2016-4343 The phar_make_dirstream function in     ext/phar/dirstream.c in PHP before 5.6.18 and 7.x before     7.0.3 mishandles zero-size ././@LongLink files, which     allows remote attackers to cause a denial of service     (uninitialized pointer dereference) or possibly have     unspecified other impact via a crafted TAR archive.

  - CVE-2016-4537 The bcpowmod function in     ext/bcmath/bcmath.c in PHP before 5.5.35, 5.6.x before     5.6.21, and 7.x before 7.0.6 accepts a negative integer     for the scale argument, which allows remote attackers to     cause a denial of service or possibly have unspecified     other impact via a crafted call.

  - CVE-2016-4539 The xml_parse_into_struct function in     ext/xml/xml.c in PHP before 5.5.35, 5.6.x before 5.6.21,     and 7.x before 7.0.6 allows remote attackers to cause a     denial of service (buffer under-read and segmentation     fault) or possibly have unspecified other impact via     crafted XML data in the second argument, leading to a     parser level of zero.

  - CVE-2016-4540

  - CVE-2016-4541 The grapheme_strpos function in     ext/intl/grapheme/grapheme_string.c in before 5.5.35,     5.6.x before 5.6.21, and 7.x before 7.0.6 allows remote     attackers to cause a denial of service (out-of-bounds     read) or possibly have unspecified other impact via a     negative offset.

  - CVE-2016-4542

  - CVE-2016-4543

  - CVE-2016-4544 The exif_process_* function in     ext/exif/exif.c in PHP before 5.5.35, 5.6.x before     5.6.21, and 7.x before 7.0.6 does not validate IFD     sizes, which allows remote attackers to cause a denial     of service (out-of-bounds read) or possibly have     unspecified other impact via crafted header data.

According to its banner, the version of PHP running on the remote web server is 7.0.x prior to 7.0.5. It is, therefore, affected by multiple vulnerabilities :

  - A buffer over-write condition exists in the finfo_open()     function due to improper validation of magic files. An     unauthenticated, remote attacker can exploit this, via a     crafted file, to cause a denial of service or to execute     arbitrary code.

  - A flaw exists in the php_snmp_error() function within     file ext/snmp/snmp.c that is triggered when handling     format string specifiers. An unauthenticated, remote     attacker can exploit this, via a crafted SNMP object,     to cause a denial of service or to execute arbitrary     code.

  - An invalid memory write error exists when handling     the path of phar file names that allows an attacker     to have an unspecified impact.

  - A flaw exists in the mbfl_strcut() function within file     ext/mbstring/libmbfl/mbfl/mbfilter.c when handling     negative parameter values. An unauthenticated, remote     attacker can exploit this to cause a denial of service.

  - An integer overflow condition exists in the     php_raw_url_encode() function within file     ext/standard/url.c due to improper validation of     user-supplied input. An unauthenticated, remote attacker     can exploit this to have an unspecified impact.

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

A malformed magic file could trigger a segmentation fault and thus crash applications due to a buffer over-write in the file_check_mem function.

For Debian 7 'Wheezy', this problem has been fixed in version 5.11-2+deb7u9.

We recommend that you upgrade your file packages.

  - An out-of-bounds write flaw was found in the     fpm_log_write() logging function of PHP's FastCGI     Process Manager service. A remote attacker could     repeatedly send maliciously crafted requests to force     FPM to exhaust file system space, creating a denial of     service and preventing further logging.(CVE-2016-5114)

  - spl_array.c in the SPL extension in PHP before 5.5.37     and 5.6.x before 5.6.23 improperly interacts with the     unserialize implementation and garbage collection,     which allows remote attackers to execute arbitrary code     or cause a denial of service (use-after-free and     application crash) via crafted serialized     data.(CVE-2016-5771)

  - php_zip.c in the zip extension in PHP before 5.5.37,     5.6.x before 5.6.23, and 7.x before 7.0.8 improperly     interacts with the unserialize implementation and     garbage collection, which allows remote attackers to     execute arbitrary code or cause a denial of service     (use-after-free and application crash) via crafted     serialized data containing a ZipArchive     object.(CVE-2016-5773)

  - Integer overflow in the fread function in     ext/standard/file.c in PHP before 5.5.36 and 5.6.x     before 5.6.22 allows remote attackers to cause a denial     of service or possibly have unspecified other impact     via a large integer in the second     argument.(CVE-2016-5096)

  - The bcpowmod function in ext/bcmath/bcmath.c in PHP     before 5.5.35, 5.6.x before 5.6.21, and 7.x before     7.0.6 accepts a negative integer for the scale     argument, which allows remote attackers to cause a     denial of service or possibly have unspecified other     impact via a crafted call.(CVE-2016-4537)

  - The bcpowmod function in ext/bcmath/bcmath.c in PHP     before 5.5.35, 5.6.x before 5.6.21, and 7.x before     7.0.6 modifies certain data structures without     considering whether they are copies of the _zero_,
    _one_, or _two_ global variable, which allows remote     attackers to cause a denial of service or possibly have     unspecified other impact via a crafted     call.(CVE-2016-4538)

  - The file_check_mem function in funcs.c in file before     5.23, as used in the Fileinfo component in PHP before     5.5.34, 5.6.x before 5.6.20, and 7.x before 7.0.5,     mishandles continuation-level jumps, which allows     context-dependent attackers to cause a denial of     service (buffer overflow and application crash) or     possibly execute arbitrary code via a crafted magic     file.(CVE-2015-8865)

  - A flaw was 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-2015-5590)

  - Use-after-free vulnerability in the wddx_stack_destroy     function in ext/wddx/wddx.c in PHP before 5.6.26 and     7.x before 7.0.11 allows remote attackers to cause a     denial of service or possibly have unspecified other     impact via a wddxPacket XML document that lacks an     end-tag for a recordset field element, leading to     mishandling in a wddx_deserialize call.(CVE-2016-7413)

  - Integer overflow in the phar_parse_pharfile function in     ext/phar/phar.c in PHP before 5.6.30 and 7.0.x before     7.0.15 allows remote attackers to cause a denial of     service (memory consumption or application crash) via a     truncated manifest entry in a PHAR     archive.(CVE-2016-10159)

  - It was found that the exif_convert_any_to_int()     function in PHP was vulnerable to floating point     exceptions when parsing tags in image files. A remote     attacker with the ability to upload a malicious image     could crash PHP, causing a Denial of     Service.(CVE-2016-10158)

  - ext/libxml/libxml.c in PHP before 5.5.22 and 5.6.x     before 5.6.6, when PHP-FPM is used, does not isolate     each thread from libxml_disable_entity_loader changes     in other threads, which allows remote attackers to     conduct XML External Entity (XXE) and XML Entity     Expansion (XEE) attacks via a crafted XML document, a     related issue to CVE-2015-5161.(CVE-2015-8866)

  - Use-after-free vulnerability in the spl_ptr_heap_insert     function in ext/spl/spl_heap.c in PHP before 5.5.27 and     5.6.x before 5.6.11 allows remote attackers to execute     arbitrary code by triggering a failed     SplMinHeap::compare operation.(CVE-2015-4116)

  - Integer overflow in the virtual_file_ex function in     TSRM/tsrm_virtual_cwd.c in PHP before 5.5.38, 5.6.x     before 5.6.24, and 7.x before 7.0.9 allows remote     attackers to cause a denial of service (stack-based     buffer overflow) or possibly have unspecified other     impact via a crafted extract operation on a ZIP     archive.(CVE-2016-6289)

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

The file_check_mem function in funcs.c in file before 5.23, as used in the Fileinfo component in PHP before 5.5.34, 5.6.x before 5.6.20, and 7.x before 7.0.5, mishandles continuation-level jumps, which allows context-dependent attackers to cause a denial of service (buffer overflow and application crash) or possibly execute arbitrary code via a crafted magic file.
