SCOSA-2005.49

Description

PHP contains a flaw related to the safe_mode functionality that may allow a local attacker to execute arbitrary commands. The issue is due to PHP prepending the current directory to the constructed path for any command executed on a multithreaded web server. With the additional path, an attacker can bypass the safe_mode_exec_dir restriction and inject shell commands into the current directory name.
