"Updated setup package fixes security vulnerability :

An issue has been identified in Mandriva Business Server 2's setup
package where the /etc/shadow and /etc/gshadow files containing
password hashes were created with incorrect permissions, making them
world-readable (mga#14516).

This update fixes this issue by enforcing that those files are owned
by the root user and shadow group, and are only readable by those two
entities.

Note that this issue only affected new Mandriva Business Server 2
installations. Systems that were updated from previous Mandriva
versions were not affected.

This update was already issued as MDVSA-2015:184, but the latter was
withdrawn as it generated .rpmnew files for critical configuration
files, and rpmdrake might propose the user to use those basically
empty files, thus leading to loss of passwords or partition table.
This new update ensures that such .rpmnew files are not kept after the
update."
