Red Hat Bugzilla – Bug 103512
CAN-2003-0690 kdm local root via PAM
Last modified: 2007-11-30 17:06:53 EST
KDM does not check for successful completion of the pam_setcred()
call. In case of error conditions in the installed PAM modules, KDM
might grant local root access to any user with valid login
It has been reported that a certain configuration of the MIT pam_krb5
module can result in a failing pam_setcred() call leaving the
session alive and providing root access to a regular user.
This issue will be public on September 8th 2003
Erratum has been delayed until Sep15 due to additional issue being found,
CAN-2003-0692, weak session cookies used by kdm.
Erratum RHSA-2003:270 in progress.
Erratum was released on 16th September, now public.
An errata has been issued which should help the problem described in this bug report.
This report is therefore being closed with a resolution of ERRATA. For more information
