USN-8897-1: lxml vulnerabilities
Ubuntu fixes lxml flaws that can bypass URL sanitization for XSS and leak local files via untrusted XML.
34
lxml is a library for processing XML and HTML in the Python language. Prior to 6.1.0, using either of the two parsers in the default configuration (with resolve_entities=True) allows untrusted XML input to read local files. Setting the resolve_entities option explicitly to resolve_entities='internal' or resolve_entities=False disables the local file access. This vulnerability is fixed in 6.1.0.
