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.
