(Icecast denial of service vulnerability)

    There is an out-of-bounds read error in the web interface of Icecast
    when handling Basic Authorization requests. This vulnerability can
    theoretically be exploited by sending a specially crafted Authorization
    header to the server.
  
Impact :

    By exploiting this vulnerability, it is possible to crash the Icecast
    server remotely, resulting in a denial of service attack.
  
Workaround :

    There is no known workaround at this time. All users are advised to
    upgrade to the latest available version of Icecast."
