Description

PHP 5 before 5.2.3 does not enforce the open_basedir or safe_mode restriction in certain cases, which allows context-dependent attackers to determine the existence of arbitrary files by checking if the readfile function returns a string. NOTE: this issue might also involve the realpath function.

Affected products

• PHP: from 5.0.0 before 5.2.3 — fixed in 5.2.3

How to fix

Upgrade to a fixed version: PHP 5.2.3. Check the vendor advisory for mitigations.
