Red Hat Bugzilla – Bug 171175
PAM patches to /bin/su calls pam_setcred after environment copy
Last modified: 2007-11-30 17:07:08 EST
Description of problem:
pam_setcred gives the service modules a chance to set environment variables with
pam_putenv. On successful operation, the appplication may then copy the
accumulated PAM environment variables to the process environment with putenv(3).
login performs the environment copy after pam_open_session and pam_setcred have
been called. In contrast, su does it after pam_open_session but *before*
pam_setcred, and this is incorrect.
Version-Release number of selected component (if applicable):
The PAM functionality is added to the GNU su.c with coreutils-4.5.2-pam.patch.
My platform is actually on WS 3.0.
