The dissect_sdp function in epan/dissectors/packet-sdp.c in the SDP dissector in Wireshark 1.12.x before 1.12.9 does not prevent use of a negative media count, which allows remote attackers to cause a denial of service (application crash) via a crafted packet.

Double free vulnerability in epan/dissectors/packet-nlm.c in the NLM dissector in Wireshark 1.12.x before 1.12.9 and 2.0.x before 2.0.1, when the “Match MSG/RES packets for async NLM” option is enabled, allows remote attackers to cause a denial of service (application crash) via a crafted packet.

The dissect_dns_answer function in epan/dissectors/packet-dns.c in the DNS dissector in Wireshark 1.12.x before 1.12.9 mishandles the EDNS0 Client Subnet option, which allows remote attackers to cause a denial of service (application crash) via a crafted packet.

The dissect_ber_GeneralizedTime function in epan/dissectors/packet-ber.c in the BER dissector in Wireshark 1.12.x before 1.12.9 and 2.0.x before 2.0.1 improperly checks an sscanf return value, which allows remote attackers to cause a denial of service (application crash) via a crafted packet.

Buffer overflow in the tvb_uncompress function in epan/tvbuff_zlib.c in Wireshark 1.12.x before 1.12.9 and 2.0.x before 2.0.1 allows remote attackers to cause a denial of service (application crash) via a crafted packet with zlib compression.

epan/dissectors/packet-sctp.c in the SCTP dissector in Wireshark 1.12.x before 1.12.9 and 2.0.x before 2.0.1 does not validate the frame pointer, which allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a crafted packet.

The AirPDcapPacketProcess function in epan/crypt/airpdcap.c in the 802.11 dissector in Wireshark 1.12.x before 1.12.9 and 2.0.x before 2.0.1 does not validate the relationship between the total length and the capture length, which allows remote attackers to cause a denial of service (stack-based buffer overflow and application crash) via a crafted packet.

The AirPDcapDecryptWPABroadcastKey function in epan/crypt/airpdcap.c in the 802.11 dissector in Wireshark 1.12.x before 1.12.9 and 2.0.x before 2.0.1 does not verify the WPA broadcast key length, which allows remote attackers to cause a denial of service (out-of-bounds read and application crash) via a crafted packet.

The dissect_diameter_base_framed_ipv6_prefix function in epan/dissectors/packet-diameter.c in the DIAMETER dissector in Wireshark 1.12.x before 1.12.9 and 2.0.x before 2.0.1 does not validate the IPv6 prefix length, which allows remote attackers to cause a denial of service (stack-based buffer overflow and application crash) via a crafted packet.

wiretap/vwr.c in the VeriWave file parser in Wireshark 1.12.x before 1.12.9 and 2.0.x before 2.0.1 does not validate certain signature and Modulation and Coding Scheme (MCS) data, which allows remote attackers to cause a denial of service (out-of-bounds read and application crash) via a crafted file.
