 - A use-after-free error exists within file ext/snmp/snmp.c when handling garbage collection during deserialization of user-supplied input. An unauthenticated, remote attacker can exploit this to deference already freed memory, resulting in the execution of arbitrary code. (CVE-2016-6295)

 - A heap-based buffer overflow condition exists in the simplestring_addn() function within file simplestring.c due to improper validation of user-supplied input. An unauthenticated, remote attacker can exploit this to cause a denial of service condition or the execution of arbitrary code. (CVE-2016-6296)

 - An integer overflow condition exists in the php_stream_zip_opener() function within file ext/zip/zip_stream.c due to improper validation of user-supplied input when handling zip streams. An unauthenticated, remote attacker can exploit this to cause a denial of service condition or the execution of arbitrary code. (CVE-2016-6297)

 - An out-of-bounds read error exists in the GD Graphics Library (libgd), specifically in the gdImageScaleBilinearPalette() function within file gd_interpolation.c, when handling transparent color. An unauthenticated, remote attacker can exploit this to cause a denial of service condition or disclose memory contents.

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

 - A flaw exists in the curl_unescape() function within file ext/curl/interface.c when handling string lengths. An unauthenticated, remote attacker can exploit this to cause heap corruption, resulting in a denial of service condition.

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

 - A NULL write flaw exists in the GD Graphics Library (libgd) in the gdImageColorTransparent() function due to improper handling of negative transparent colors. A remote attacker can exploit this to disclose memory contents.

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

icu was updated to fix two security issues.

These security issues were fixed :

Versions of PHP 5.5.x prior to 5.5.38, or 5.6.x prior to 5.6.24, or 7.0.x prior to 7.0.9 are vulnerable to the following issues :

 - A NULL pointer dereference flaw within the '_gdScaleVert()' function inside of 'ext/gd/libgd/gd_interpolation.c' is triggered during the handling of '_gdContributionsCalc' return values. This may allow a remote attacker to cause a denial of service in a process linked against PHP.
 - A flaw related to missing protection against 'RFC 3875 section 4.1.18' namespace conflicts is triggered when handling requests containing 'Proxy' HTTP headers. These may be stored in the 'HTTP_PROXY' environment variable also commonly used to configure an outbound HTTP proxy for applications. With a specially crafted request, a remote attacker can specify an arbitrary HTTP proxy server to be used by applications relying on the HTTP_PROXY environment variable. (CVE-2016-5385)
 - An out-of-bounds read flaw within the 'gdImageScaleBilinearPalette()' function inside of 'gd_interpolation.c' is triggered when handling transparent colors. This may allow a context-dependent attacker to crash a process linked against the library or potentially disclose memory contents.
 - A flaw within the 'gdImageScaleTwoPass()' function inside of 'gd_interpolation.c' is triggered as certain input is not properly validated. This may allow a context-dependent attacker to crash a process linked against the library. (CVE-2016-6207)
 - A use-after-free error within 'ext/snmp/snmp.c' is triggered during the unserialization of user-supplied input when handling garbage collection. This may allow a remote attacker to dereference already freed memory and potentially execute arbitrary code. (CVE-2016-6295)
 - An out-of-bounds read flaw within the 'uloc_acceptLanguageFromHTTP()' function inside of 'common/uloc.cpp' may allow a remote attacker to crash a program using the language or potentially disclose memory contents. (CVE-2016-6293, CVE-2016-6294)
 - A use-after-free error within 'ext/session/session.c' is triggered during the handling of 'var_hash destruction'. This may allow a remote attacker to dereference already freed memory and potentially execute arbitrary code. (CVE-2016-6290)
 - An out-of-bounds read flaw within the 'exif_process_IFD_in_MAKERNOTE()' function inside of 'ext/exif/exif.c' may allow a remote attacker to crash a program using the language or potentially disclose memory contents. (CVE-2016-6291)
 - An overflow condition within the 'php_bz2iop_read()' function inside of 'ext/bz2/bz2.c' is triggered as error conditions are not properly handled. With a specially crafted request, a remote attacker can cause a buffer overflow and potentially execute arbitrary code. (CVE-2016-5399)
 - An overflow condition within the 'mdecrypt_generic()' function inside of 'ext/mcrypt/mcrypt.c' is triggered as user-supplied input is not properly validated. This may allow a remote attacker to cause a heap-based buffer overflow, crashing a program using the language or potentially allowing the execution of arbitrary code.
 - A NULL pointer dereference flaw within the 'exif_process_user_comment()' function inside of 'ext/exif/exif.c' may allow a remote attacker to crash a program using the language. (CVE-2016-6292)
 - A flaw within the 'curl_unescape()' function inside of 'ext/curl/interface.c' is triggered during the handling of string lengths. This may allow a remote attacker to trigger heap corruption and crash a program using the language.
 - An overflow condition within the 'mcrypt_generic()' function inside of 'ext/mcrypt/mcrypt.c' is triggered as user-supplied input is not properly validated. This may allow a remote attacker to cause a heap-based buffer overflow, resulting in a denial of service or potentially allowing the execution of arbitrary code.
 - An integer overflow condition within the 'php_stream_zip_opener()' function inside of 'ext/zip/zip_stream.c' is triggered as user-supplied input is not properly validated when handling zip streams. This may allow a remote attacker to cause a stack-based buffer overflow, crashing a program using the language or potentially allowing the execution of arbitrary code. (CVE-2016-6297)
 - An integer overflow condition within the 'virtual_file_ex()' function inside of 'Zend/zend_virtual_cwd.c' is triggered as user-supplied input is not properly validated when handling variables. This may allow a remote attacker to cause a stack-based buffer overflow, crashing a program using the language or potentially allowing the execution of arbitrary code. (CVE-2016-6289)
 - An overflow condition within the 'simplestring_addn()' function inside of 'simplestring.c.' is triggered as user-supplied input is not properly validated. This may allow a context-dependent attacker to cause a heap-based buffer overflow, resulting in a denial of service in a process linked against the library or potentially allowing the execution of arbitrary code. (CVE-2016-6296)
 - A NULL write flaw within the 'gdImageColorTransparent()' function inside of 'gd.c' is triggered during the handling of negative transparent colors. This may allow a context-dependent attacker to disclose memory.
 - An overflow condition within the 'php_url_prase_ex()' function inside of 'ext/standard/url.c' is triggered as user-supplied input is not properly validated. This may allow a remote attacker to cause a buffer overflow, potentially resulting in a denial of service in a process utilizing the language. (CVE-2016-6288)

According to its banner, the version of PHP running on the remote web server is 7.0.x prior to 7.0.9. It is, therefore, affected by multiple vulnerabilities :

An     unauthenticated, remote attacker can exploit this to     cause a denial of service condition or the execution of     arbitrary code. (CVE-2016-6297)

  - An out-of-bounds read error exists in the GD Graphics     Library (libgd), specifically in the     gdImageScaleBilinearPalette() function within file     gd_interpolation.c, when handling transparent color. An     unauthenticated, remote attacker can exploit this to     cause a denial of service condition or disclose     memory contents.

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

  - A NULL write flaw exists in the GD Graphics Library     (libgd) in the gdImageColorTransparent() function due to     improper handling of negative transparent colors. A     remote attacker can exploit this to disclose memory     contents.

According to its banner, the version of PHP running on the remote web server is 5.5.x prior to 5.5.38. It is, therefore, affected by multiple vulnerabilities :

  - A Segfault condition occurs when accessing     nvarchar(max) defined columns. (CVE-2015-8879)

  - A man-in-the-middle vulnerability exists, known as     'httpoxy', due to a failure to properly resolve     namespace conflicts in accordance with RFC 3875 section     4.1.18. The HTTP_PROXY environment variable is set based     on untrusted user data in the 'Proxy' header of HTTP     requests. The HTTP_PROXY environment variable is used by     some web client libraries to specify a remote proxy     server. An unauthenticated, remote attacker can exploit     this, via a crafted 'Proxy' header in an HTTP request,     to redirect an application's internal HTTP traffic to an     arbitrary proxy server where it may be observed or     manipulated. (CVE-2016-5385)

  - An overflow condition exists in the php_bz2iop_read()     function within file ext/bz2/bz2.c due to improper     handling of error conditions. An unauthenticated, remote     attacker can exploit this, via a crafted request, to     execute arbitrary code. (CVE-2016-5399)

  - A flaw exists in the GD Graphics Library (libgd),     specifically in the gdImageScaleTwoPass() function     within file gd_interpolation.c, due to improper     validation of user-supplied input. An unauthenticated,     remote attacker can exploit this to cause a denial of     service condition. (CVE-2016-6207)

  - A buffer overflow condition exists in the     php_url_parse_ex() function. (CVE-2016-6288)

  - An integer overflow condition exists in the     virtual_file_ex() function within file     Zend/zend_virtual_cwd.c due to improper validation of     user-supplied input. An unauthenticated, remote attacker     can exploit this to cause a denial of service condition     or the execution of arbitrary code. (CVE-2016-6289)

  - A use-after-free error exists within the file     ext/session/session.c when handling 'var_hash'     destruction. An unauthenticated, remote attacker can     exploit this to deference already freed memory,     resulting in the execution of arbitrary code.
    (CVE-2016-6290)

  - An out-of-bounds read error exists in the     exif_process_IFD_in_MAKERNOTE() function within file     ext/exif/exif.c. An unauthenticated, remote attacker can     exploit this to cause a denial of service condition or     disclose memory contents. (CVE-2016-6291)

  - A NULL pointer dereference flaw exists in the     exif_process_user_comment() function within file     ext/exif/exif.c. An unauthenticated, remote attacker can     exploit this to cause a denial of service condition.
    (CVE-2016-6292)

  - Multiple out-of-bounds read errors exist in the     locale_accept_from_http() function within file     ext/intl/locale/locale_methods.c. An unauthenticated,     remote attacker can exploit these to cause a denial of     service condition or disclose memory contents.
    (CVE-2016-6293, CVE-2016-6294)

  - A use-after-free error exists within file     ext/snmp/snmp.c when handling garbage collection during     deserialization of user-supplied input. An     unauthenticated, remote attacker can exploit this to     deference already freed memory, resulting in the     execution of arbitrary code. (CVE-2016-6295)

  - A heap-based buffer overflow condition exists in the     simplestring_addn() function within file simplestring.c     due to improper validation of user-supplied input. An     unauthenticated, remote attacker can exploit this to     cause a denial of service condition or the execution of     arbitrary code. (CVE-2016-6296)

  - An integer overflow condition exists in the     php_stream_zip_opener() function within file     ext/zip/zip_stream.c due to improper validation of     user-supplied input when handling zip streams. An     unauthenticated, remote attacker can exploit this to     cause a denial of service condition or the execution of     arbitrary code. (CVE-2016-6297)

  - An out-of-bounds read error exists in the GD Graphics     Library (libgd), specifically in the     gdImageScaleBilinearPalette() function within file     gd_interpolation.c, when handling transparent color. An     unauthenticated, remote attacker can exploit this to     cause a denial of service condition or disclose     memory contents.

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

  - A NULL write flaw exists in the GD Graphics Library     (libgd) in the gdImageColorTransparent() function due to     improper handling of negative transparent colors. A     remote attacker can exploit this to disclose memory     contents.

  - An overflow condition exists in the php_url_prase_ex()     function due to improper validation of user-supplied     input. A remote attacker can exploit this to cause a     buffer overflow, resulting in a denial of service     condition.
