+ BASH PATCH REPORT
+ =================
+
+Bash-Release: 4.3
+Patch-ID: bash43-048
+
+Bug-Reported-by: up201407890@alunos.dcc.fc.up.pt
+Bug-Reference-ID: <20151210201649.126444eionzfsam8@webmail.alunos.dcc.fc.up.pt>
+Bug-Reference-URL: http://lists.gnu.org/archive/html/bug-bash/2015-12/msg00054.html
+
+Bug-Description:
+
+If a malicious user can inject a value of $SHELLOPTS containing `xtrace'
+and a value for $PS4 that includes a command substitution into a shell
+running as root, bash will expand the command substitution as part of
+expanding $PS4 when it executes a traced command.
+
+Patch (apply with `patch -p0'):
