[TYPO3-core] RFC bug: #16797: t3lib_stdGraphic::wrapFileName performs escapeshellarg even in safe_mode

[Jigal van Hemert]

Hi,

This is a SVN patch request.

Type: Bugfix

BT reference: http://bugs.typo3.org/view.php?id=16797

Branches: trunk

Problem:
When safe_mode is on PHP will perform escapeshellcmd on each command 
sent to the exec() function. When escapeshellarg() is performed on each 
argument problem characters are escaped twice.

Solution:
only perform escapeshellarg() when safe_mode is off.

Notes:
This used to be part of #13750.
