-Subject: [PATCH] Fix security framework bypass
-
-xsltCheckRead and xsltCheckWrite return -1 in case of error but callers
-don't check for this condition and allow access. With a specially
-crafted URL, xsltCheckRead could be tricked into returning an error
-because of a supposedly invalid URL that would still be loaded
-succesfully later on.
-
-Fixes #12.
-
-Thanks to Felix Wilhelm for the report.
