Bug#58520: rexec segfaults
I just had a look at:
Package: rexec (debian/main)
Maintainer: Herbert Xu <firstname.lastname@example.org>
58520 rexec segfaults
The segfault occurs within rexec() when called with either
user or passwd set to NULL. There was a patch in 1.4 to work
around this. Herbert has comments in 1.5-2 indicating he
removed this intentionally because it is a libc6 problem.
It seems a shame to lose rexec to the "Bug Horizon" if this
doesn't get reassigned in time. A simple workaround is to
us -n to force user/passwd prompt "rexec -n localhost ls".
