tag_insight = "brltty (Braille TTY) is a background process (daemon) which provides access
  to the Linux console (when in text mode) for a blind person using a
  refreshable braille display. It drives the braille display, and provides
  complete screen review functionality.

  It was discovered that a brltty library had an insecure relative RPATH
  (runtime library search path) set in the ELF (Executable and Linking
  Format) header. A local user able to convince another user to run an
  application using brltty in an attacker-controlled directory, could run
  arbitrary code with the privileges of the victim. (CVE-2008-3279)
  
  These updated packages also provide fixes for the following bugs:
  
  * the brltty configuration file is documented in the brltty manual page,
  but there is no separate manual page for the /etc/brltty.conf configuration
  file: running "man brltty.conf" returned "No manual entry for brltty.conf"
  rather than opening the brltty manual entry. This update adds brltty.conf.5
  as an alias to the brltty manual page. Consequently, running "man
  brltty.conf" now opens the manual entry documenting the brltty.conf
  specification. (BZ#530554)
  
  * previously, the brltty-pm.conf configuration file was installed in the
  /etc/brltty/ directory. This file, which configures Papenmeier Braille
  Terminals for use with Red Hat Enterprise Linux, is optional. As well, it
  did not come with a corresponding manual page. With this update, the file
  has been moved to /usr/share/doc/brltty-3.7.2/BrailleDrivers/Papenmeier/.
  This directory also includes a README document that explains the file's
  purpose and format. (BZ#530554)
  
  * during the brltty packages installation, the message
  
  Creating screen inspection device /dev/vcsa...done.
  
  was presented at the console. This was inadequate, especially during the
  initial install of the system. These updated packages do not send any
  message to the console during installation. (BZ#529163)
  
  * although brltty contains ELF objects, the brltty-debuginfo package was
  empty. With this update, the -debuginfo package contains valid debugging
  information as expected. (BZ#500545)
  
  * the MAX_NR_CONSOLES definition was acquired by brltty by #including
  linux/tty.h in Programs/api_client.c. MAX_NR_CONSOLES has since moved to
  linux/vt.h but the #include in api_client.c was not updated. Consequently,
  brltty could not be built from the source RPM against the Red Hat
  Enterprise Linux 5 kernel. This update corrects the #include in
  api_client.c to linux/vt.h and brltty now builds from source as expected.
  (BZ#456247)
  
  All brltty users are advised to upgrade to these updated packages, which
  resolve these issues.";
