PHP 5.5.x < 5.5.30 / 5.6.x < 5.6.14 Multiple Vulnerabilities

high Nessus Network Monitor Plugin ID 8956
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

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

Description

Versions of PHP 5.5.x prior to 5.5.30, or 5.6.x prior to 5.6.14 are vulnerable to the following issues :

- A NULL pointer dereference flaw affects the phar_get_fp_offset() function in 'ext/phar/util.c' that is triggered when pointing to a non-existent file. This may allow a remote attacker to cause a denial of service.
- An uninitialized pointer flaw affects the phar_make_dirstream() function in 'lext/phar/dirstream.c' that is triggered when handling a zip entry filename that is '/', which can result in a crash or potentially a data leak.

Solution

Upgrade to PHP version 5.6.14, or later. If 5.6.x cannot be obtained, 5.5.30 is also patched for these vulnerabilities.
