Nagios Plugins 2.0.2 Released

The Nagios Plugins Development Team is proud to announce that nagios-plugins 2.0.2 has been released and is available for download.

This release was prompted a bit earlier than originally expected by a newly discovered security vulnerability reported by Dawid Golunski on exploit-db. It concerned an arbitrary file access vulnerability with the SUID binaries (check_icmp, check_dhcp) and the extra-opts configure flag (which is enabled by default).  Fixes were applied globally, so the new restrictions on fopen should apply to all plugins.

Additionally, a few plugins were updated to successfully build on windows under cygwin, and some small changes were made to plugin output and verbosity.

A full list of included enhancements and fixes are listed below:

SECURITY FIXES

  • Fixed file access vulnerability with SUID binaries (check_icmp, check_dhcp) and extra-opts.  Fixes were applied globally, so the new resrictions on fopen should apply to all plugins. Special thanks to Dawid Golunski for the submission. More information: http://www.exploit-db.com/exploits/33387/  (sreinhardt) (emislivec)

ENHANCEMENTS

  • check_disk – Now compiles in cygwin on windows (Gunnar Beutner)
  • check_ping – Now compiles in cygwin on windows (Gunnar Beutner)
  • check_users – Now compiles in cygwin on windows (Gunnar Beutner)
  • netutils.c – Connection error verbosity increased. C plugins will now differentiate file socket errors from connection errors (Davide Madrisan)

FIXES

  • check_nt.c – Changed ‘Mb’ to ‘MB’ in MEMUSE output for clarity (abrist)
