CVE-2014-8476: Infoleak
First published: Thu Nov 13 2014(Updated: )
The setlogin function in FreeBSD 8.4 through 10.1-RC4 does not initialize the buffer used to store the login name, which allows local users to obtain sensitive information from kernel memory via a call to getlogin, which returns the entire buffer.
