CVE-2012-0862 low priority: Ubuntu including 1 source packages (xinetd), 24 status rows across 24 suites (artful, bionic, cosmic, disco, eoan, focal, groovy, hardy, hirsute, lucid, natty, oneiric, precise, quantal, raring, saucy, trusty, upstream, utopic, vivid, wily, xenial, yakkety, zesty): not-affected 18, ignored 5, released 1.
builtins.c in Xinetd before 2.3.15 does not check the service type when the tcpmux-server service is enabled, which exposes all enabled services and allows remote attackers to bypass intended access restrictions via a request to tcpmux port 1.
