WEBrick 1.3.1 in Ruby 1.8.6 through patchlevel 383, 1.8.7 through patchlevel
248, 1.8.8dev, 1.9.1 through patchlevel 376, and 1.9.2dev writes data to a log file
without sanitizing non-printable characters, which might allow remote attackers
to modify a window’s title, or possibly execute arbitrary commands or overwrite
files, via an HTTP request containing an escape sequence for a terminal emulator.
