Ruby: Denial of Service

Ruby: Denial of Service Ruby WEBrick and XMLRPC servers are vulnerable to Denial of Service. ruby May 10, 2006 May 10, 2006: 01 130657 remote 1.8.4-r1 1.8.4-r1

Ruby is an interpreted scripting language for quick and easy object-oriented programming. It comes bundled with HTTP ("WEBrick") and XMLRPC server objects.

Ruby uses blocking sockets for WEBrick and XMLRPC servers.

An attacker could send large amounts of data to an affected server to block the socket and thus deny other connections to the server.

There is no known workaround at this time.

All Ruby users should upgrade to the latest version:


    # emerge --sync
    # emerge --ask --oneshot --verbose ">=dev-lang/ruby-1.8.4-r1"
