Vulnerability Assessment Details

MDKSA-2006:185: php

Vulnerability Assessment Summary
Check for the version of the php package

Detailed Explanation for this Vulnerability Assessment

The remote host is missing the patch for the advisory MDKSA-2006:185 (php).

PHP 4.x up to 4.4.4 and PHP 5 up to 5.1.6 permits local users to bypass
certain Apache HTTP Server httpd.conf options, such as safe_mode and
open_basedir, via the ini_restore function, which resets the values to
their php.ini (Master Value) defaults. (CVE-2006-4625)
A race condition in the symlink function in PHP 5.1.6 and earlier
permits local users to bypass the open_basedir restriction by using a
combination of symlink, mkdir, and unlink functions to change the file
path after the open_basedir check and before the file is opened by the
underlying system, as demonstrated by symlinking a symlink into a
subdirectory, to point to a parent directory via .. (dot dot)
sequences, and then unlinking the resulting symlink. (CVE-2006-5178)
Because the design flaw cannot be solved it is strongly recommended to
disable the symlink() function if you are using the open_basedir
feature. You can achieve that by adding symlink to the list of disabled
functions within your php.ini: disable_functions=...,symlink
The updated packages do not alter the system php.ini.
Updated packages have been patched to correct the CVE-2006-4625 issue.
Users must restart Apache for the changes to take effect.
