epan/dissectors/packet-gmr1_bcch.c in the GMR-1 BCCH dissector in Wireshark 1.8.x before 1.8.8 does not properly initialize memory, which allows remote attackers to cause a denial of service (application crash) via a crafted packet.

The vwr_read function in wiretap/vwr.c in the Ixia IxVeriWave file parser in Wireshark 1.8.x before 1.8.8 does not validate the relationship between a record length and a trailer length, which allows remote attackers to cause a denial of service (heap-based buffer overflow and application crash) via a crafted packet.

Buffer overflow in the dissect_iphc_crtp_fh function in epan/dissectors/packet-ppp.c in the PPP dissector in Wireshark 1.8.x before 1.8.8 allows remote attackers to cause a denial of service (application crash) via a crafted packet.

The http_payload_subdissector function in epan/dissectors/packet-http.c in the HTTP dissector in Wireshark 1.6.x before 1.6.16 and 1.8.x before 1.8.8 does not properly determine when to use a recursive approach, which allows remote attackers to cause a denial of service (stack consumption) via a crafted packet.

schpw.c in the kpasswd service in kadmind in MIT Kerberos 5 (aka krb5) before 1.11.3 does not properly validate UDP packets before sending responses, which allows remote attackers to cause a denial of service (CPU and bandwidth consumption) via a forged packet that triggers a communication loop, as demonstrated by krb_pingpong.nasl, a related issue to CVE-1999-0103.

Multiple integer signedness errors in the tvb_unmasked function in epan/dissectors/packet-websocket.c in the Websocket dissector in Wireshark 1.8.x before 1.8.7 allow remote attackers to cause a denial of service (application crash) via a malformed packet.

The fragment_add_seq_common function in epan/reassemble.c in the ASN.1 BER dissector in Wireshark before r48943 has an incorrect pointer dereference during a comparison, which allows remote attackers to cause a denial of service (application crash) via a malformed packet.

The dissect_ber_choice function in epan/dissectors/packet-ber.c in the ASN.1 BER dissector in Wireshark 1.6.x before 1.6.15 and 1.8.x before 1.8.7 does not properly initialize a certain variable, which allows remote attackers to cause a denial of service (application crash) via a malformed packet.

epan/dissectors/packet-gtpv2.c in the GTPv2 dissector in Wireshark 1.8.x before 1.8.7 calls incorrect functions in certain contexts related to ciphers, which allows remote attackers to cause a denial of service (application crash) via a malformed packet.

Multiple integer overflows in Wireshark 1.8.x before 1.8.7 allow remote attackers to cause a denial of service (loop or application crash) via a malformed packet, related to a crash of the Websocket dissector, an infinite loop in the MySQL dissector, and a large loop in the ETCH dissector.
