Red Hat Security Advisory: : New util-linux packages available to fix /bin/login pam problem
New util-linux packages are available that fix a problem with /bin/login's PAM implementation. This could, in some non-default setups, cause users to receive credentials of other users. It is recommended that all users update to the fixed packages. 2001-10-22: Packages are now available for Red Hat Linux 7.2. Notably, these packages also fix the problem noted in RHSA-2001:095-04 (vipw incorrectly setting permissions on some files) - this bug was accidentally reintroduced in Red Hat Linux 7.2.
