Package name util-linux
Date February 13th, 2003
Advisory ID MDKSA-2003:016
Affected versions 8.2, 9.0
Synopsis Updated util-linux packages provide stronger randomness in mcookie

Problem 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.
