Description Tomas Hoger 2015-06-17 18:59:50 UTC

It was discovered that DOMDocument's save() and saveHTMLFile(), and GD imagepsencodefont() function did not properly handle file names with NUL character.  This could cause the functions to access unexpected files when their arguments come from untrusted source.  These issues are related to fixes for CVE-2015-3411 / CVE-2015-3412 which cover different functions from these extensions - see bug 1213407 comment 5.
