Description Oleg Makarenko 2004-06-08 09:05:44 UTC 
From Bugzilla Helper:
User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0)

Description of problem:
pppd segfaults with signal 11 when ms-chap authentication is used.

The problem is with sha1.c file that assumes that unsigned long is 32-
bits wide (on AMD64 in is 64-bits wide).

Possible solutions are:

1. get rid of sha1.c and use openssl's sha implementation. that 
requires some trivial pppd patching

or 

2. Patch sha1.c to use int32 instead of unsigned long (for example as 
in

)

I would prefer to link in libcrypto.


Version-Release number of selected component (if applicable):
ppp-2.4.2-2

How reproducible:
Always

Steps to Reproduce:
run pppd in ms-chap mode
    

Actual Results:  pppd died with signal 11 message in /var/log/message
