| Descripción: | Multiple buffer overflows in libXML 2.6.12 and 2.6.13 (libxml2), and
possibly other versions, may allow remote attackers to execute
arbitrary code via (1) a long FTP URL that is not properly handled by
the xmlNanoFTPScanURL function, (2) a long proxy URL containing FTP
data that is not properly handled by the xmlNanoFTPScanProxy function,
and other overflows related to manipulation of DNS length values,
including (3) xmlNanoFTPConnect, (4) xmlNanoHTTPConnectHost, and (5)
xmlNanoHTTPConnectHost.
