Signed integer vulnerability in libnasl in Nessus before 2.0.6 allows local users with plugin upload privileges to cause a denial of service (core dump) and possibly execute arbitrary code by causing a negative argument to be provided to the insstr function as used in a NASL script.

Multiple buffer overflows in libnasl in Nessus before 2.0.6 allow local users with plugin upload privileges to cause a denial of service (core dump) and possibly execute arbitrary code via (1) a long proto argument to the scanner_add_port function, (2) a long user argument to the ftp_log_in function, (3) a long pass argument to the ftp_log_in function.

Multiple unknown vulnerabilities in Nessus before 2.0.6, in libnessus and possibly libnasl, a different set of vulnerabilities than those identified by CVE-2003-0372 and CVE-2003-0373, aka "similar issues in other nasl functions as well as in libnessus."
