Patch we use in pkgsrc, tested on sparc and mips

On NetBSD, which uses 64bit time_t, and architectures that require strict alignement (and are 32bit) the blob allocation in pwutil.c causes unaligned accesses and makes sudo/visudo dump core.

I've made a more invasive fix for sudo 1.8.5.  Can you verify that ftp://ftp.sudo.ws/pub/sudo/beta/sudo-1.8.5rc5.tar.gz works correctly?  A similar diff will appear in the next sudo 1.7.x release.

This works fine, thanks for the quick fix!

Comment 3 Todd C. Miller 2012-09-12 15:05:36 MDT

Fixed in sudo 1.8.5 and 1.7.10.
