Description Svyatoslav Lempert 2012-05-09 03:29:07 EDT
Description of problem:

file_exists() silently truncates anything after a null byte in a string.  This produces unexpected results in some circumstances and possibly would result in security problems for limited amounts of poorly written code.

include_once() for instance, provides the following:
"ALERT - Include filename truncated by a \0 after '/etc/passwd' (attacker 'REMOTE_ADDR not set', file '/home/djc/test.php', line 13)"

This seems like a sane way to handle it if truncating has to be done... though frankly since truncation will *always* produce the wrong result it might be nice to throw an error and stop processing.
