CVE-2006-7243

Description

PHP before 5.3.4 accepts the \0 character in a pathname, which might allow context-dependent attackers to bypass intended access restrictions by placing a safe file extension after this character, as demonstrated by .php\0.jpg at the end of the argument to the file_exists function. #### Bugs * <http://bugs.php.net/39863> #### Notes Author| Note ---|--- [sbeattie](<https://launchpad.net/~sbeattie>) | upstream only prepared a fix for the 5.3 tree. Backporting the fix to 5.2.x requires modifying php APIs.
