Multiple use-after-free vulnerabilities in epan/dissectors/packet-wccp.c in the WCCP dissector in Wireshark 1.10.x before 1.10.12 and 1.12.x before 1.12.3 allow remote attackers to cause a denial of service (application crash) via a crafted packet, related to the use of packet-scope memory instead of pinfo-scope memory.

The dissect_wccp2r1_address_table_info function in epan/dissectors/packet-wccp.c in the WCCP dissector in Wireshark 1.10.x before 1.10.12 and 1.12.x before 1.12.3 does not initialize certain data structures, which allows remote attackers to cause a denial of service (application crash) via a crafted packet.

asn1/lpp/lpp.cnf in the LPP dissector in Wireshark 1.10.x before 1.10.12 and 1.12.x before 1.12.3 does not validate a certain index value, which allows remote attackers to cause a denial of service (out-of-bounds memory access and application crash) via a crafted packet.

Multiple use-after-free vulnerabilities in epan/dissectors/packet-dec-dnart.c in the DEC DNA Routing Protocol dissector in Wireshark 1.10.x before 1.10.12 and 1.12.x before 1.12.3 allow remote attackers to cause a denial of service (application crash) via a crafted packet, related to the use of packet-scope memory instead of pinfo-scope memory.

epan/dissectors/packet-smtp.c in the SMTP dissector in Wireshark 1.10.x before 1.10.12 and 1.12.x before 1.12.3 uses an incorrect length value for certain string-append operations, which allows remote attackers to cause a denial of service (application crash) via a crafted packet.

Buffer underflow in the ssl_decrypt_record function in epan/dissectors/packet-ssl-utils.c in Wireshark 1.10.x before 1.10.12 and 1.12.x before 1.12.3 allows remote attackers to cause a denial of service (application crash) via a crafted packet that is improperly handled during decryption of an SSL session.
