"A security vulnerability has been identified and fixed in login
application from shadow-utils, which could allow local users in the
utmp group to overwrite arbitrary files via a symlink attack on a
temporary file referenced in a line (aka ut_line) field in a utmp
entry (CVE-2008-5394).

The updated packages have been patched to prevent this.

default, and therefore is not affected by this issue on default
configuration."
