libxslt: security framework bypass (CVE-2019-11068)
libxslt through 1.1.33 allows bypass of a protection mechanism because
callers of xsltCheckRead and xsltCheckWrite permit access even upon
receiving a –1 error code. xsltCheckRead can return –1 for a crafted URL that is not actually invalid and is subsequently loaded.
