The README from this release follows. Please read it carefully.

This document is intended to describe the significant differences between hylafax-4.2.5 and older releases, point out any known incompatibilites and issues, and provide the reader with directions to further resources regarding HylaFAX.

New Features

  • Security fix – hfaxd vulnerability CVE-2005-3538
  • Security fix – script vulnerability CVE-2005-3539
  • PAM support on Solaris
  • Local/GMT timezone support in JOBFMT/RECVFMT formatters
  • numerous other enhancements and bug fixes (see CHANGES)

Known Issues

Please refer to HylaFAX Bugzilla for a detailed list of issues.


  • Some modem config files generated from earlier versions’ config file prototypes may contain Class1TCFRecvHack. This is no longer desirable for production use, and this feature should now only be used for debugging purposes.
  • The time value of %Z in jobfmt/recvfmt is now returned in GMT time when GMT is requested, and in local time when local time is requested. Previously, %Z was always returned in local time, even if GMT had been requested.
  • If upgrading from any release older than 4.2.2, be advised that CIDName/CIDNumber are now part of a larger CallID framework.
  • libtiff-3.6.1 is fatally flawed when dealing with Group 3 images. Don’t use it as-is. See: http://bugs.hylafax.org/bugzilla/show_bug.cgi?id=500

Who Should Upgrade?

For security reasons, everyone should consider upgrading to this 4.2.5 release as soon as possible. Anyone who upgraded to 4.2.4 during its short lifetime should also upgrade, otherwise faxrcvd and notify may not function as expected.
