Buffer overflow in the MAC-LTE dissector (epan/dissectors/packet-mac-lte.c) in Wireshark 1.2.0 through 1.2.13 and 1.4.0 through 1.4.2 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a large number of RARs.

Heap-based buffer overflow in the dissect_ldss_transfer function (epan/dissectors/packet-ldss.c) in the LDSS dissector in Wireshark 1.2.0 through 1.2.12 and 1.4.0 through 1.4.1 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via an LDSS packet with a long digest line that triggers memory corruption.

Stack consumption vulnerability in the dissect_ber_unknown function in epan/dissectors/packet-ber.c in the BER dissector in Wireshark 1.4.x before 1.4.1 and 1.2.x before 1.2.12 allows remote attackers to cause a denial of service (NULL pointer dereference and crash) via a long string in an unknown ASN.1/BER encoded packet, as demonstrated using SNMP.
