According to its banner, the version of PHP running on the remote web server is 7.0.x prior to 7.0.13. It is, therefore, affected by multiple vulnerabilities :

 - A flaw exists in the parse_url() function due to returning the incorrect host. An unauthenticated, remote attacker can exploit this to have a multiple impacts depending on how the function is implemented, which can include bypassing authentication or conducting open redirection and server-side request forgery attacks.

 - An integer overflow condition exists in the _php_imap_mail() function in file ext/imap/php_imap.c when handling overly long strings. An unauthenticated, remote attacker can exploit this to cause a heap-based buffer overflow, resulting in a denial of service condition or the execution of arbitrary code.

 - An integer overflow condition exists in the gdImageAALine() function within file ext/gd/libgd/gd.c due to improper validation of line limit values. An unauthenticated, remote attacker can exploit this to cause an out-of-bounds memory read or write, resulting in a denial of service condition, the disclosure of memory contents, or the execution of arbitrary code.

Note that this software is reportedly affected by other vulnerabilities as well that have not been fixed yet in version 7.0.13.

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 5.6.x prior to 5.6.28 and 7.0.x prior to 7.0.13 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 integer overflow condition exists in the '_php_imap_mail()' function in 'ext/imap/php_imap.c' that is triggered when handling overly long strings. This may allow a remote attacker to cause a heap-based buffer overflow, leading to a crash or the potential execution of arbitrary code.
 - A flaw exists that is triggered when handling overly long strings passed to the 'bzcompress()' PHP method. This may allow a remote attacker to cause a denial of service.
 - An integer overflow condition exists in the 'gdImageAALine()' function in 'ext/gd/libgd/gd.c' that is triggered as line limit values are not properly validated. This may allow a remote attacker to cause an out-of-bounds write or read flaw, which may potentially allow the attacker to crash a process utilizing the language, disclose memory contents, or execute arbitrary code.
 - An infinite loop flaw exists in the 'exception::__toString()' function in 'Zend/zend_exceptions.c' that is triggered during the unserialization of self-referencing exception objects. This may allow a remote attacker to cause a denial of service.

According to its banner, the version of PHP running on the remote web server is 7.0.x prior to 7.0.13. It is, therefore, affected by multiple vulnerabilities :

  - A stack consumption condition exists in the     gdImageFillToBorder function of the gd.c script within     the GD Graphics Library (libgd). An unauthenticated,     remote attacker can exploit this issue, via a crafted     call to imagefilltoborder using a negative color value,     to cause the application to stop responding.
    (CVE-2016-9933)

  - A denial of service (DoS) vulnerability exists in the     ext/wddx/wddx.c script. An unauthenticated, remote     attacker can exploit this issue, via crafted serialized     data in a wddxPacket XML document, to cause the     application to stop responding. (CVE-2016-9934)

  - A flaw exists in the parse_url() function due to     returning the incorrect host. An unauthenticated, remote     attacker can exploit this to have a multiple impacts     depending on how the function is implemented, which can     include bypassing authentication or conducting open     redirection and server-side request forgery attacks.

  - An integer overflow condition exists in the
    _php_imap_mail() function in file ext/imap/php_imap.c     when handling overly long strings. An unauthenticated,     remote attacker can exploit this to cause a     heap-based buffer overflow, resulting in a denial of     service condition or the execution of arbitrary code.

  - An integer overflow condition exists in the     gdImageAALine() function within file ext/gd/libgd/gd.c     due to improper validation of line limit values. An     unauthenticated, remote attacker can exploit this to     cause an out-of-bounds memory read or write, resulting     in a denial of service condition, the disclosure of     memory contents, or the execution of arbitrary code.

Note that this software is reportedly affected by other vulnerabilities as well that have not been fixed yet in version 7.0.13.

  - A denial of service flaw exists due to a flaw in     Zend/zend_exceptions.c via a crafted Exception object     in serialized data (CVE-2016-7478)

  - A Stack consumption vulnerability in the     gdImageFillToBorder function in gd.c in the GD Graphics     Library could lead to a denial of service condition.
