states that this book is aimed at systems administrators who are not
security experts, but have some responsibility for ensuring the integrity
of their systems. That would seem to cover most sysadmins.

| Package: util-linux | ----------------------------//
| Date: 02-13-2003 |
+---------------------------------+
Description:
The util-linux package provides the mcookie utility, a tool for generating
random cookies that can be used for X authentication. The util-linux
packages that were distributed with Mandrake Linux 8.2 and 9.0 had a patch
that made it use /dev/urandom instead of /dev/random, which resulted in
the mcookie being more predictable than it would otherwise be. This patch
has been removed in these updates, giving mcookie a better source of
entropy and making the generated cookies less predictable. Thanks to Dirk
Mueller for pointing this out.

| Package: pam | ----------------------------//
| Date: 02-18-2003 |
+---------------------------------+
Description:
Andreas Beck discovered that the pam_xauth module would forward
authorization information from the root account to unprivileged users.
This can be exploited by a local attacker to gain access to the root
user's X session. In order for it to be successfully exploited, the
attacker would have to somehow get the root user to su to the account
belonging to the attacker.
