+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.
