Red Hat Product Errata RHSA-2003:270 normal SHIPPED_LIVE Moderate: kdebase security update 2003-09-16 04:00:00 UTC

Description Mark J. Cox 2003-09-01 15:20:00 UTC
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

Comment 2 Mark J. Cox 2003-09-09 11:58:24 UTC
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.

Comment 3 Mark J. Cox 2003-09-16 20:18:52 UTC
Erratum was released on 16th September, now public.
