Description Martin McClure 2004-11-24 20:32:42 UTC

pppd/sha1.c in net-dialup/ppp has a number of "unsigned long" declarations, which it assumes are 32 bits. This causes crashes on 64-bit architectures (I've only tested with amd64, but I would think it's true of anything with 64-bit longs). This is fixed in the recently-released upstream ppp 2.4.3. It is also fixed in the mppe-mppc patch that is applied when built with USE=mppe-mppc.

One possible fix, for versions prior to 2.4.3, would be to always apply the mppe-mppc patch on 64-bit architectures, regardless of the USE flag.

Reproducible: Always
Steps to Reproduce:
1.Build ppp 2.4.2 -mppe-mppc
2. Build pptp-client
3. Attempt to open a tunnel to a PPTP server that uses CHAP.

Actual Results:  
"Fatal Signal 11"

Expected Results:  
Continued to negotiate the tunnel.

Well, if 2.4.3 is fixed by the upstream then this bug is fixed in our repository too. I've released an ebuild for ppp-2.4.3 on 27 Nov 2004.
