Red Hat Product Errata RHSA-2003:289 0 high SHIPPED_LIVE Important: XFree86 security update 2003-11-12 05:00:00 UTC

Description Mark J. Cox 2003-09-18 13:30:23 UTC 
xdm does not verify whether the pam_setcred
function call succeeds, which may allow attackers to gain root
privileges by triggering error conditions within PAM modules,
as demonstrated in certain configurations of the MIT pam_krb5
module.
