"According to its banner, the version of MiniUPnP running on the remote
host is prior to 1.4. It is, therefore, affected by the following
vulnerabilities :

  - An out-of-bounds read error exists in the
    ProcessSSDPRequest() function in file minissdp.c that
    allows an unauthenticated, remote attacker to cause a
    denial of service condition via a specially crafted
    M-SEARCH request. (CVE-2013-0229)

  - A stack-based buffer overflow condition exists in the
    ExecuteSoapAction() function in the SOAPAction handler,
    due to improper validation of user-supplied input. An
    unauthenticated, remote attacker can exploit this, via a
    long quoted method, to cause a denial of service
    condition or the execution of arbitrary code.
    (CVE-2013-0230)");
