According to its banner, the version of PHP running on the remote web server is 7.0.x prior to 7.0.23 or 7.1.x prior to 7.1.9, therefore, affected by a heap user after free vulnerability when unserializing invalid array size.

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 7.0.23. It is, therefore, affected by a heap-based buffer overflow condition exists in the ext/standard/var_unserializer.re script due to improper use of the hash API for key deletion. An unauthenticated, remote attacker can exploit this to cause a denial of service condition or the execution of arbitrary code.

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

The remote host is affected by the vulnerability described in GLSA-201709-21 (PHP: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in PHP. Please review the       referenced CVE identifiers for details.
  Impact :

    A remote attacker could execute arbitrary code with the privileges of       the process or cause a Denial of Service condition.
  Workaround :

    There is no known workaround at this time.

Several vulnerabilities were found in PHP, a widely-used open source general purpose scripting language :

  - CVE-2017-11144     Denial of service in openssl extension due to incorrect     return value check of OpenSSL sealing function

  - CVE-2017-11145     Out-of-bounds read in wddx_deserialize()

  - CVE-2017-11628     Buffer overflow in PHP INI parsing API

  - CVE-2017-12932 / CVE-2017-12934     Use-after-frees during unserialisation

  - CVE-2017-12933     Buffer overread in finish_nested_data()

  - CVE-2017-16642     Out-of-bounds read in timelib_meridian()

According to its banner, the version of PHP running on the remote web server is 7.1.x prior to 7.1.9. It is, therefore, affected by a heap-based buffer overflow condition exists in the ext/standard/var_unserializer.re script due to improper use of the hash API for key deletion. An unauthenticated, remote attacker can exploit this to cause a denial of service condition or the execution of arbitrary code.

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

This update for php7 fixes several issues.

These security issues were fixed :

  - CVE-2017-12932: Prevent heap use after free while     unserializing untrusted data, related to improper use of     the hash API for key deletion in a situation with an     invalid array size. Exploitation of this issue could     have had an unspecified impact on the integrity of PHP     (bsc#1054432).

  - CVE-2017-12934: Prevent heap use after free while     unserializing untrusted data, related to the     zval_get_type function in Zend/zend_types.h.
    Exploitation of this issue could have had an unspecified     impact on the integrity of PHP (bsc#1054408).

  - CVE-2017-12933: The finish_nested_data function in     ext/standard/var_unserializer.re was prone to a buffer     over-read while unserializing untrusted data.
    Exploitation of this issue could have had an unspecified     impact on the integrity of PHP (bsc#1054430)

These non-security issues were fixed :

  - bsc#1057104: php7-devel now requires php7-pear

  - bsc#1057845: Fixed namespace encapsulation of imported     classes/functions/constants
