Two vulnerabilities were discovered in yaws, a high performance HTTP 1.1 webserver written in Erlang.

- CVE-2020-24379 The WebDAV implementation is prone to a XML External Entity (XXE) injection vulnerability.

- CVE-2020-24916 The CGI implementation does not properly sanitize CGI requests allowing a remote attacker to execute arbitrary shell commands via specially crafted CGI executable names.
