PHP 5.6.x < 5.6.14 Multiple Vulnerabilities

high Nessus Plugin ID 86301

Language:

Synopsis

The remote web server uses a version of PHP that is affected by multiple vulnerabilities.

Description

According to its banner, the version of PHP running on the remote web server is 5.6.x prior to 5.6.14. It is, therefore, affected by multiple vulnerabilities :

- A NULL pointer dereference flaw exists in the phar_get_fp_offset() function in ext/phar/util.c that is triggered when pointing to a non-existent file. An unauthenticated, remote attacker can exploit this to cause a denial of service condition. (CVE-2015-7803)

- An uninitialized pointer flaw exists in the phar_make_dirstream() function in ext/phar/dirstream.c that is triggered when handling a zip entry filename that is a single forward slash. An unauthenticated, remote attacker can exploit this to cause a denial of service condition or to disclose sensitive information.
(CVE-2015-7804)

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

Solution

Upgrade to PHP version 5.6.14 or later.
