Debian Security Advisory DSA-4773-1 security@debian.org

Package : yaws
CVE ID : CVE-2020-24379 CVE-2020-24916
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.
For the stable distribution (buster), these problems have been fixed in
version 2.0.6+dfsg-1+deb10u1.
We recommend that you upgrade your yaws packages.
For the detailed security status of yaws please refer to its security
tracker page at:
