Bug 113128 – mail-filter/libspf2 not 64 bit safe in spf_interpret.c

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Olivier Hill 2005-11-20 20:14:14 UTC]

As reported by Carsten Koch-Mauthe, libspf2-1.2.5 is not 64 bit safe.

This can cause Exim to segfault if it was configured to use spf.

You can see the complete report at:
http://www.gossamer-threads.com/lists/spf/devel/24280?do=post_view_threaded

The solution is to simply declare the buflen variable as size_t instead of int.

I have created a patch and will try to attach it to the bug report.

Reproducible: Always
Steps to Reproduce:
emerge libspf
USE="spf" emerge exim

Start Exim and wait for some emails to come by.
Actual Results:  
Look at dmesg, you should see the following:
exim[11307]: segfault at 0000000000616000 rip 00002aaaabe25a73 rsp
00007fffffbffea8 error 6

Sending this amd64 way, been sitting here for ages and it concerns mainly them, after all.
