CVE-2007-1710
The readfile function in PHP 4.4.4, 5.1.6, and 5.2.1 allows context-dependent attackers to bypass safe_mode restrictions and read arbitrary files by referring to local files with a certain URL syntax instead of a pathname syntax, as demonstrated by a filename preceded a "php://../../" sequence.
