epan/dissectors/packet-rlc in the RLC dissector in Wireshark 1.8.x before 1.8.13 and 1.10.x before 1.10.6 uses inconsistent memory-management approaches, which allows remote attackers to cause a denial of service (use-after-free error and application crash) via a crafted UMTS Radio Link Control packet.
Buffer overflow in the mpeg_read function in wiretap/mpeg.c in the MPEG parser in Wireshark 1.8.x before 1.8.13 and 1.10.x before 1.10.6 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a large record in MPEG data.
