Vulnerability Id:        CVE-2004-0989
Vulnerability Scope:     global (not OpenPKG specific)

Attack Feasibility:      run-time
Attack Vector:           
Attack Impact:           arbitrary code execution

Description:
    According to BUGTRAQ posting [0], multiple vulnerabilities exist in
    the XML parsing library libxml [1]. Multiple buffer overflows may
    allow remote attackers to execute arbitrary code via a long FTP URL
    that is not properly handled by the "xmlNanoFTPScanURL" function,
    a long proxy URL containing FTP data that is not properly handled
    by the "xmlNanoFTPScanProxy" function, and other overflows related
    to the manipulation of DNS length values in "xmlNanoFTPConnect",
    "xmlNanoHTTPConnectHost", and "xmlNanoHTTPConnectHost".
