+ BASH PATCH REPORT
+ =================
+
+Bash-Release: 4.2
+Patch-ID: bash42-044
+
+Bug-Reported-by: "Dashing" <dashing@hushmail.com>
+Bug-Reference-ID: <20130211175049.D90786F446@smtp.hushmail.com>
+Bug-Reference-URL: http://lists.gnu.org/archive/html/bug-bash/2013-02/msg00030.html
+
+Bug-Description:
+
+When converting a multibyte string to a wide character string as part of
+pattern matching, bash does not handle the end of the string correctly,
+causing the search for the NUL to go beyond the end of the string and
+reference random memory. Depending on the contents of that memory, bash
+can produce errors or crash.
+
+Patch (apply with `patch -p0'):
