Looks like the current version of HylaFax in the ports once again has 
security issues (remote and local).

 From the web page http://www.hylafax.org/4.1.3.html

4.1.3 includes fixes for a remote format string vulnerability which could 
be abused in a denial of service attack. Also fixed is a buffer overflow 
condition when receiving fax image data which potentially could be 
exploited to execute arbitrary code as root. Also present in 4.1.3 are 
fixes for several other local remote format string vulnerabilities which, 
in some installations, could lead to elevated privileges by abuse. Everyone 
is advised to upgrade.

------------------------------
I am not a heavy user of HylaFax (only outbound), but removing the two 
patch files and making the following changes lets it build with the new 
source code.  The md5 is also on the webpage.
