Trustix Secure Linux Security Advisory #2001-0025

Package name:      Util-linux
Summary:           Possible to gain some other user's credentials
Date:              2001-10-17
Affected versions: TSL 1.5

- --------------------------------------------------------------------------

Problem description:
  The "login" program in util-linux stored the user's credentials in a
  static buffer that could later be reused in other PAM calls issued on
  behalf of other users.  This could lead to a user gaining access to
  other accounts.
  Note that this is not possible by default.

Action:
  We recommend that all systems with this package installed are upgraded.
