DESCRIPTION
Screen[1] is a program which allows the use of several sessions
inside a single terminal.
Timo Sirainen reported[2] a buffer overflow vulnerability[3] in the
screen package which could be exploited by an attacker who is able to
send about 2Gb of data to the user's screen session.
Additionally, a fix for a potential problem with window sizes has
been incorporated in these updated packages.
Please note that screen is not installed setuid/setgid.
SOLUTION
It is recommended that all screen users upgrade their packages.
