shellinabox was updated to version 2.20 to fix the following security issues :

  • It was possible to fallback to the HTTP protocol even when configured for HTTPS. (CVE-2015-8400, boo#957748)

  • Disable secure client-initiated renegotiation

  • Set SSL options for increased security (disable SSLv2, SSLv3)

  • Protection against large HTTP requests

non security fixes :

  • Includes some MSIE and iOS rendering fixes
