COMMAND
screen (3.7.2)
SYSTEMS AFFECTED
FreeBSD 2.1.5-RELEASE
PROBLEM
Nathan Torkington wrote that it's possible to send a signal 11 to
the latest version of screen (3.7.2) and make it coredump with
the master.passwd file in memory.
SOLUTION
Upgrade to 2.1.6 (preferably, wait a few days for 2.1.7) In OS
versions 2.1.6 and greater suid programs will not dump core.
