HylaFAX 4.1.8 Release


The HylaFAX development team is pleased to announce our 4.1.8 patch-level release! This is a security release that fixes a remotely exploitable format string vulnerability in hfaxd that could be present in certain non-default configurations. As always, our sincerest thanks goes to all who participate and provide feedback. We'd like to extend a special thank-you to Sebastian Krahmer and the SuSE Security Team for discovering this issue.

The source code for the 4.1.8 release can be downloaded from:

  • Specific support for fax class 1.0 is not yet implemented.
  • A low-priority job can block a high priority job to the same destination.
  • Newer versions of awk produce odd xferfaxstats output (use --nomap).
Please refer to HylaFAX Bugzilla for a detailed list of issues.


  • HylaFAX source needs to be extracted and built on a case-sensitive filesystem. Users with case-insensitive filesystems, such as those with Mac OS X HFS, will need to mount a new filesystem (i.e. UFS) for this purpose. A patch is available which makes this unnecessary. See http://bugs.hylafax.org/bugzilla/show_bug.cgi?id=370 for more info.
