Directory traversal vulnerability in PHP 5.2.4 and earlier allows attackers to bypass open_basedir restrictions and possibly execute arbitrary code via a .. (dot dot) in the dl function.
The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.
