CVS commit: src/dist/openpam/lib

["Matthias Drochner" <drochner%netbsd.org@localhost>]

Module Name:    src
Committed By:   drochner
Date:           Wed Nov  9 20:26:41 UTC 2011

Modified Files:
        src/dist/openpam/lib: openpam_configure.c

Log Message:
Don't allow '/' characters in the "service" argument to pam_start()
The "service" is blindly appended to config directories ("/etc/pam.d/"),
and if a user can control the "service" it can get PAM to read config
files from any location.
This is not a problem with most software because the "service" is
usually a constant string. The check protects 3rd party software
from being abused.
