Tenable Releases Nessus 2.2.6

November 8, 2005

Columbia, MD

Nessus 2.2.6 has been released today. It is a maintenance release which fixes several minor bugs, adds a new function to the NASL language and contains an improved version of the Nessus TCP scanner. We recommend to every Nessus 2.2 user to upgrade to this version. Here is a quick summary of the changes and improvements in this release:

Changes affecting the Nessus engine:

  • Fixed a problem which would prevent nessusd from starting up properly when the system clock is not configured properly
  • Under certain circumstances, the plugins preferences may appear twice in the Nessus GUI
  • nessus-fetch is more reliable when used in a very low bandwidth environment
  • nessusd has higher memory limits when running on a 64 bits CPU
  • New NASL function socket_get_error() which returns the last error which occurred on a socket (timeout, connection reset, etc...)
  • Removed the C function http_recv_headers() in favor of http_recv_headers2() written in NASL


Changes affecting the Nessus plugins:

  • The Windows Bulletin checks now check the version of the files on the remote host (when possible) instead of looking at the registry
  • It is now possible to disable CGI scanning entirely in the "Global Settings" preference panel
  • Rewritten several key plugins (dcetest.nasl, netbios_name_get.nasl) to better support the underlying protocol
  • nessus_tcp_scanner now performs multiple passes, for improved reliability. It also is much quicker against BSD machines (which have a rate limitation for the RST they send)
