+[NETFILTER]: nf_conntrack_h323: add checking of out-of-range on choices' index
values
+
+Choices' index values may be out of range while still encoded in the fixed
+length bit-field. This bug may cause access to undefined types (NULL
+pointers) and thus crashes (Reported by Zhongling Wen).
+
+This patch also adds checking of decode flag when decoding SEQUENCEs.
