BASH PATCH REPORT
=================
Bash-Release: 4.3
Patch-ID: bash43-009
Bug-Reported-by: Matthias Klose <doko@debian.org>
Bug-Reference-ID: <53346FC8.6090005@debian.org>
Bug-Reference-URL: http://lists.gnu.org/archive/html/bug-bash/2014-03/msg00171.html
Bug-Description:
There is a problem with unsigned sign extension when attempting to reallocate
the input line when it is fewer than 3 characters long and there has been a
history expansion. The sign extension causes the shell to not reallocate the
line, which results in a segmentation fault when it writes past the end.
