Several issues have been discovered in PHP (recursive acronym for PHP:
Hypertext Preprocessor), a widely-used open source general-purpose scripting language that is especially suited for web development and can be embedded into HTML.

CVE-2016-7478: Zend/zend_exceptions.c in PHP allows remote attackers to cause a denial of service (infinite loop) via a crafted Exception object in serialized data, a related issue to CVE-2015-8876.

CVE-2016-7479: During the unserialization process, resizing the 'properties' hash table of a serialized object may lead to use-after-free. A remote attacker may exploit this bug to gain the ability of arbitrary code execution. Even though the property table issue only affects PHP 7 this change also prevents a wide range of other __wakeup() based attacks.

CVE-2017-7272: The fsockopen() function will use the port number which is defined in hostname instead of the port number passed to the second parameter of the function. This misbehavior may introduce another attack vector for an already known application vulnerability (e.g.
Server Side Request Forgery).

For Debian 7 'Wheezy', these problems have been fixed in version 5.4.45-0+deb7u8.

We recommend that you upgrade your php5 packages.

Check Point reports :

... discovered 3 fresh and previously unknown vulnerabilities (CVE-2016-7479, CVE-2016-7480, CVE-2016-7478) in the PHP 7 unserialize mechanism.

The first two vulnerabilities allow attackers to take full control over servers, allowing them to do anything they want with the website, from spreading malware to defacing it or stealing customer data.

The last vulnerability generates a Denial of Service attack which basically hangs the website, exhausts its memory consumption, and shuts it down.

The PHP security team issued fixes for two of the vulnerabilities on the 13th of October and 1st of December.

Versions of PHP prior to 7.1.0 are vulnerable to the following issues :

 - A flaw exists that is due to 'parse_url' returning the incorrect host. This may allow a remote attacker to have an impact that may include bypassing authentication, or conducting open redirection and server-side request forgery attacks, depending on how the function is implemented.
 - An overflow condition exists in the 'dynamicGetbuf()' function in 'gd_io_dp.c'. The issue is triggered as certain input is not properly validated. With a specially crafted string, a remote attacker can cause a stack-based buffer overflow, resulting in a denial of service in a process utilizing the language or potentially allowing the execution of arbitrary code.
 - A use-after-free error exists in the 'unserialize()' function related to uses of '__wakeup' which modify properties. This may allow a remote attacker to dereference already freed memory and potentially execute arbitrary code.
 - A use-after-free error exists that is triggered when handling unserialized object properties. With a specially crafted request, a remote attacker can dereference already freed memory and potentially execute arbitrary code.

According to its banner, the version of PHP running on the remote web server is 7.1.x prior to 7.1.1. It is, therefore, affected by the following vulnerabilities :

  - A use-after-free error exists that is triggered when     handling unserialized object properties. An     unauthenticated, remote attacker can exploit this, via a     specially crafted request, to execute arbitrary code.
    (CVE-2016-7479)

  - An integer overflow condition exists in the
    _zend_hash_init() function in zend_hash.c due to     improper validation of unserialized objects. An     unauthenticated, remote attacker can exploit this to     execute arbitrary code. (CVE-2017-5340)

  - A floating pointer exception flaw exists in the     exif_convert_any_to_int() function in exif.c that is     triggered when handling TIFF and JPEG image tags. An     unauthenticated, remote attacker can exploit this to     cause a crash, resulting in a denial of service     condition. (CVE-2016-10158)

  - An out-of-bounds read error exists in the     finish_nested_data() function in var_unserializer.c due     to improper validation of unserialized data. An     unauthenticated, remote attacker can exploit this to     cause a crash, resulting in a denial of service     condition or the disclosure of memory contents.
    (CVE-2016-10161)

  - A NULL pointer dereference flaw exists in the     php_wddx_pop_element() function in wddx.c due to     improper validation of user-supplied input. An     unauthenticated, remote attacker can exploit this to     cause a crash, resulting in a denial of service     condition. (CVE-2016-10162)

  - An signed integer overflow condition exists in gd_io.c     due to improper validation of user-supplied input. An     unauthenticated, remote attacker can exploit this to     have an unspecified impact.

  - A denial of service vulnerability exists in the bundled     GD Graphics Library (LibGD) in the     gdImageCreateFromGd2Ctx() function in gd_gd2.c due to     improper validation of images. An unauthenticated,     remote attacker can exploit this, via a specially     crafted image, to crash the process. (CVE-2016-10167)

   - An integer overflow condition exists in the gd_io.c      script of the GD Graphics Library (libgd). An      unauthenticated, remote attacker can exploit this to      cause a denial of service condition or the execution of      arbitrary code. (CVE-2016-10168)

  - An out-of-bounds read error exists in the     phar_parse_pharfile() function in phar.c due to improper     parsing of phar archives. An unauthenticated, remote     attacker can exploit this to cause a crash, resulting in     a denial of service condition. (CVE-2017-11147)

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

Integer overflow in gd_io.c in the GD Graphics Library (aka libgd) before 2.2.4 allows remote attackers to have unspecified impact via vectors involving the number of horizontal and vertical chunks in an image. (CVE-2016-10168)

In all versions of PHP 7, during the unserialization process, resizing the 'properties'; hash table of a serialized object may lead to use-after-free. A remote attacker may exploit this bug to gain arbitrary code execution. (CVE-2016-7479)

 - A denial of service vulnerability exists in the bundled GD Graphics Library (LibGD) in the gdImageCreateFromGd2Ctx() function in gd_gd2.c due to improper validation of images. An unauthenticated, remote attacker can exploit this, via a specially crafted image, to crash the process. (CVE-2016- 10167)

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

According to its banner, the version of PHP running on the remote web server is 7.0.x prior to 7.0.15. It is, therefore, affected by the following vulnerabilities :

 - A remote code execution vulnerability exists due to a use-after-free error in the unserialize() function that is triggered when using DateInterval input. An unauthenticated, remote attacker can exploit this to dereference already freed memory, resulting in a denial of service condition or the execution of arbitrary code. (CVE-2015-2787)

 - A use-after-free error exists that is triggered when handling unserialized object properties. An unauthenticated, remote attacker can exploit this, via a specially crafted request, to execute arbitrary code. (CVE-2016-7479)

 - An integer overflow condition exists in the _zend_hash_init() function in zend_hash.c due to improper validation of unserialized objects. An unauthenticated, remote attacker can exploit this to execute arbitrary code. (CVE-2017-5340)

 - A floating pointer exception flaw exists in the exif_convert_any_to_int() function in exif.c that is triggered when handling TIFF and JPEG image tags. An unauthenticated, remote attacker can exploit this to cause a crash, resulting in a denial of service condition. (CVE-2016-10158)

 - An integer overflow condition exists in the phar_parse_pharfile() function in phar.c due to improper validation when handling phar archives. An unauthenticated, remote attacker can exploit this to cause a crash, resulting in a denial of service condition. (CVE-2016-10159)

 - An off-by-one overflow condition exists in the phar_parse_pharfile() function in phar.c due to improper parsing of phar archives. An unauthenticated, remote attacker can exploit this to cause a crash, resulting in a denial of service condition. (CVE-2016-10160)

 - An out-of-bounds read error exists in the finish_nested_data() function in var_unserializer.c due to improper validation of unserialized data. An unauthenticated, remote attacker can exploit this to cause a crash, resulting in a denial of service condition or the disclosure of memory contents. ( CVE-2016-10161)

 - A NULL pointer dereference flaw exists in the php_wddx_pop_element() function in wddx.c due to improper validation of user-supplied input. An unauthenticated, remote attacker can exploit this to cause a crash, resulting in a denial of service condition. (CVE-2016-10162)

 - An signed integer overflow condition exists in gd_io.c due to improper validation of user-supplied input. An unauthenticated, remote attacker can exploit this to have an unspecified impact.

 - A type confusion flaw exists that is triggered during the deserialization of specially crafted GMP objects. An unauthenticated, remote attacker can exploit this to cause a crash, resulting in a denial of service condition.

 - A type confusion error exists that is triggered when deserializing ZVAL objects. An unauthenticated, remote attacker can exploit this to execute arbitrary code.

 - An out-of-bounds read error exists in the phar_parse_pharfile() function in phar.c due to improper parsing of phar archives. An unauthenticated, remote attacker can exploit this to cause a crash, resulting in a denial of service condition.

 - A denial of service vulnerability exists in the bundled GD Graphics Library (LibGD) in the gdImageCreateFromGd2Ctx() function in gd_gd2.c due to improper validation of images. An unauthenticated, remote attacker can exploit this, via a specially crafted image, to crash the process.
