Hi,

The following vulnerability was published for libxslt.

CVE-2019-11068[0]:
| 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.


If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
