(KVIrc: Remote arbitrary code execution)

    Stefan Cornelius from Secunia Research discovered that the
    'parseIrcUrl()' function in file src/kvirc/kernel/kvi_ircurl.cpp does
    not properly sanitise parts of the URI when building the command for
    KVIrc's internal script system.
  
Impact :

    A remote attacker could entice a user to open a specially crafted
    irc:// URI, possibly leading to the remote execution of arbitrary code
    with the privileges of the user running KVIrc. Successful exploitation
    requires that KVIrc is registered as the default handler for irc:// or
    similar URIs.
  
Workaround :

    There is no known workaround at this time."
