Tenable is pleased to announce the release of Nessus 5.0.1! This is a point release (moving from 5.0 to 5.0.1), containing enhancements and minor bug fixes. This release improves the stability on all platforms, and solves Windows-specific issues related to installation and packet forgery.

New features

From a user perspective, the only change is that it is now possible to specify a separate list of UDP and TCP ports to scan on all targets. This is set in the "Port scanner range" field when you create a new policy or modify an existing one (e.g. if you wanted to scan TCP ports 1-1024 and UDP ports 1-200 the syntax is: "T:1-1024,U:1-200"). Also, a build for FreeBSD version 9 is now available.

Enhancements & Bug Fixes

 In addition, several enhancements and bug fixes are included:

  • Resolved an issue whereas packet forgery was not working on some Windows setups
  • Improved the Windows installer which would fail on some setups
  • Fixed several thread synchronization issues leading to a crash in certain situations
  • Imported v1 reports are more legible
  • Nessus can now read a 64-bit database on a 32-bit system and vice-versa
  • Identified and resolved a minor memory leak issue occurring on all platforms
  • Scanning with a SSL certificate defined in the policy would sometimes cause a scanner crash
  • Workaround for CVE-2011-3389
  • Worked around a possible incompatibility with the Fedora 16 / Debian 6 memory allocator
  • Restored the ability to log in via certificate authentication on port 1241 when "force_pubkey_auth = no"
  • This version of Nessus now includes OpenSSL version 1.0.0h
