[sudo-users] Just an FYI...

[Larry Becke]

The version of sudo that Oracle bundles with Solaris 11.2, which is 
based off of Sudo version 1.8.9p5, exposes a known bug in the Solaris 
ksh binary.

Bug 18647317 - ksh cores on Solaris 11.1 SRU 16.5 and above

Steps to replicate

login to a server where your account home directory is locked down to 
your account access, ie perms set to 0700

$ id
loginuser
$ sudo -u otheruser -s
$ id
otheruser
$  pwd
Bus Error
$ id
loginuser

The workaround of course is to use sudo -u otheruser -i

I am still waiting on Oracle to resolve Bug 18647317
