Red Hat Product Errata RHSA-2004:188 normal SHIPPED_LIVE Important: Updated kernel packages available for Red Hat Enterprise Linux 3 Update 2 2004-05-11 04:00:00 UTC

Description Mark J. Cox 2004-01-08 15:25:43 UTC
CAN-2003-0461 /proc/tty/driver/serial in Linux 2.4.x reveals the exact
number of characters used in serial links, which could allow local
users to obtain potentially sensitive information such as the length
of passwords.


This is a minor issue but should be addressed with some future

Comment 1 Mark J. Cox 2004-01-08 15:26:24 UTC
(note not fixed in 2.4.21-7.EL)

Comment 3 Ernie Petrides 2004-02-11 05:54:14 UTC
A fix for this problem has just been committed to the RHEL3 U2
patch pool tonight.  It will first be available in kernel version

The /proc/tty/driver directory will now have permissions of 500
(i.e., root-only access).
