According to its banner, the version of PHP running on the remote web server is 7.1.x prior to 7.1.0. It is, therefore, affected by the following 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 deserialization vulnerability exists in the     ext/standard/var.c script. An unauthenticated, remote     attacker can exploit this, via crafted serialized data,     to the application to stop responding or execute     arbitrary code on the target host. (CVE-2016-9936)

Note that Nessus 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 7.0.14. It is, therefore, affected by a remote code execution vulnerability due to a memory corruption issue in the php_wddx_push_element() function in ext/wddx/wddx.c that occurs when decoding empty boolean elements. An unauthenticated, remote attacker can exploit this to cause a denial of service condition or the execution of arbitrary code.

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

This update for php7 fixes the following issues :

  - CVE-2016-9933 Possible stack overflow on truecolor     images handling [bsc#1015187]

  - CVE-2016-9934 Dereference from NULL pointer could lead     to crash [bsc#1015188]

  - CVE-2016-9935 Invalid read could lead to crash     [bsc#1015189]

  - CVE-2016-9936 Use After free in the function serialize()     could lead to crash [bsc#1015191]

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

USN-3211-1 fixed vulnerabilities in PHP by updating to the new 7.0.15 upstream release. PHP 7.0.15 introduced a regression when using MySQL with large blobs. This update fixes the problem with a backported fix.

The SplObjectStorage unserialize implementation in ext/spl/spl_observer.c in PHP before 7.0.12 does not verify that a key is an object, which allows remote attackers to execute arbitrary code or cause a denial of service (uninitialized memory access) via crafted serialized data. (CVE-2016-7480)

Use-after-free vulnerability in the CURLFile implementation in ext/curl/curl_file.c in PHP 7.x before 7.0.12 allows remote attackers to cause a denial of service or possibly have unspecified other impact via crafted serialized data that is mishandled during __wakeup processing. (CVE-2016-9137)

Stack consumption vulnerability in the gdImageFillToBorder function in gd.c in the GD Graphics Library (aka libgd) before 2.2.2, as used in PHP 7.x before 7.0.13, allows remote attackers to cause a denial of service (segmentation violation) via a crafted imagefilltoborder call that triggers use of a negative color value. (CVE-2016-9933)

ext/wddx/wddx.c in PHP 7.x before 7.0.13 allows remote attackers to cause a denial of service (NULL pointer dereference) via crafted serialized data in a wddxPacket XML document, as demonstrated by a PDORow string. (CVE-2016-9934)

The php_wddx_push_element function in ext/wddx/wddx.c in PHP 7.x before 7.0.14 allows remote attackers to cause a denial of service (out-of-bounds read and memory corruption) or possibly have unspecified other impact via an empty boolean element in a wddxPacket XML document. (CVE-2016-9935)

The unserialize implementation in ext/standard/var.c in PHP 7.x before 7.0.14 allows remote attackers to cause a denial of service (use-after-free) or possibly have unspecified other impact via crafted serialized data. This vulnerability exists because of an incomplete fix for CVE-2015-6834 . (CVE-2016-9936)

This update for php7 fixes the following issues :

  - CVE-2016-9933 Possible stack overflow on truecolor     images handling [bsc#1015187]

  - CVE-2016-9934 Dereference from NULL pointer could lead     to crash [bsc#1015188]

  - CVE-2016-9935 Invalid read could lead to crash     [bsc#1015189]

  - CVE-2016-9936 Use After free in the function serialize()     could lead to crash [bsc#1015191]

This update was imported from the SUSE:SLE-12:Update update project.

The PHP project reports :

- Use After Free Vulnerability in unserialize() (CVE-2016-9936)

- Invalid read when wddx decodes empty boolean element (CVE-2016-9935)

Versions of PHP 7.0.x prior to 7.0.14 are vulnerable to a use-after-free error in the 'unserialize()' function in 'ext/standard/var.c'. This may allow a remote attacker to dereference already freed memory and potentially execute arbitrary code.

According to its banner, the version of PHP running on the remote web server is 7.0.x prior to 7.0.14. It is, therefore, affected by the following vulnerabilities:

  -  A remote code execution vulnerability due to a memory      corruption issue in the php_wddx_push_element()      function in ext/wddx/wddx.c that occurs when decoding      empty boolean elements. An unauthenticated, remote      attacker can exploit this to cause a denial of service      condition or the execution of arbitrary code.
     (CVE-2016-9935)

  - A deserialization vulnerability exists in the     ext/standard/var.c script. An unauthenticated, remote     attacker can exploit this, via crafted serialized data,     to the application to stop responding or execute     arbitrary code on the target host. (CVE-2016-9936)

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