Andries Brouwer Util-linux 2.10s

The PAM implementation in /bin/login of the util-linux package before 2.11 causes a password entry to be rewritten across multiple PAM calls, which could provide the credentials of one user to a different user, when used in certain PAM modules such as pam_limits.

vipw in the util-linux package before 2.10 causes /etc/shadow to be world-readable in some cases, which would make it easier for local users to perform brute force password guessing.
