Description

PHP before 5.4.42 5.5.x before 5.5.26 and 5.6.x before 5.6.10 does not ensure that pathnames lack 00 sequences which might allow remote attackers to read or write to arbitrary files via crafted input to an application that calls (1) a DOMDocument save method or (2) the GD imagepsloadfont function as demonstrated by a filename\0.html attack that bypasses an intended configuration in which client users may write to only .html files.
