+Subject: [PATCH] plug-ins: Fix ZDI-CAN-25100 for FLI plug-in
+
+Resolves #13073
+This patch adds a check to make sure we're not
+writing beyond the bounds of the "pos" array.
+This is the same check that we do earlier when
+writing pos[xc++], but it was left off of the last
+write command. Since "n" will be 0 if we get to the
+end of the array, it prevents us from writing beyond
+that.
