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.
