From e03553605b45c88f0b4b2980adfbbb8f6fca2fd6 Mon Sep 17 00:00:00 2001

Subject: 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.
