Buffer overflow in OPC UA applications allows remote attackers to trigger a stack overflow with carefully structured requests.
In Wireshark 2.6.0 to 2.6.2, 2.4.0 to 2.4.8, and 2.2.0 to 2.2.16, the Bluetooth AVDTP dissector could crash. This was addressed in epan/dissectors/packet-btavdtp.c by properly initializing a data structure.
In Wireshark 2.6.0 to 2.6.2, 2.4.0 to 2.4.8, and 2.2.0 to 2.2.16, the Radiotap dissector could crash. This was addressed in epan/dissectors/packet-ieee80211-radiotap-iter.c by validating iterator operations.
In Wireshark 2.6.0 to 2.6.2, 2.4.0 to 2.4.8, and 2.2.0 to 2.2.16, the Bluetooth Attribute Protocol dissector could crash. This was addressed in epan/dissectors/packet-btatt.c by verifying that a dissector for a specific UUID exists.
In Wireshark 2.6.0 to 2.6.1 and 2.4.0 to 2.4.7, the IEEE 802.11 protocol dissector could crash. This was addressed in epan/crypt/airpdcap.c via bounds checking that prevents a buffer over-read.
In Wireshark 2.6.0 to 2.6.1, 2.4.0 to 2.4.7, and 2.2.0 to 2.2.15, the HTTP2 dissector could crash. This was addressed in epan/dissectors/packet-http2.c by verifying that header data was found before proceeding to header decompression.
In Wireshark 2.6.0 to 2.6.1, 2.4.0 to 2.4.7, and 2.2.0 to 2.2.15, the Bazaar protocol dissector could go into an infinite loop. This was addressed in epan/dissectors/packet-bzr.c by properly handling items that are too long.
In Wireshark 2.6.0 to 2.6.1 and 2.4.0 to 2.4.7, the CoAP protocol dissector could crash. This was addressed in epan/dissectors/packet-coap.c by properly checking for a NULL condition.
In Wireshark 2.6.0 to 2.6.1, 2.4.0 to 2.4.7, and 2.2.0 to 2.2.15, the ISMP dissector could crash. This was addressed in epan/dissectors/packet-ismp.c by validating the IPX address length to avoid a buffer over-read.
In Wireshark 2.6.0 to 2.6.1, 2.4.0 to 2.4.7, and 2.2.0 to 2.2.15, the ASN.1 BER dissector could crash. This was addressed in epan/dissectors/packet-ber.c by ensuring that length values do not exceed the maximum signed integer.
In Wireshark 2.6.0 to 2.6.1, 2.4.0 to 2.4.7, and 2.2.0 to 2.2.15, the BGP protocol dissector could go into a large loop. This was addressed in epan/dissectors/packet-bgp.c by validating Path Attribute lengths.
In Wireshark 2.6.0 to 2.6.1, 2.4.0 to 2.4.7, and 2.2.0 to 2.2.15, the DICOM dissector could go into a large or infinite loop. This was addressed in epan/dissectors/packet-dcm.c by preventing an offset overflow.
In Wireshark 2.6.0 to 2.6.1, 2.4.0 to 2.4.7, and 2.2.0 to 2.2.15, dissectors that support zlib decompression could crash. This was addressed in epan/tvbuff_zlib.c by rejecting negative lengths to avoid a buffer over-read.
In Wireshark 2.6.0 to 2.6.1, 2.4.0 to 2.4.7, and 2.2.0 to 2.2.15, the MMSE dissector could go into an infinite loop. This was addressed in epan/proto.c by adding offset and length validation.
In Wireshark 2.6.0, 2.4.0 to 2.4.6, and 2.2.0 to 2.2.14, the LDSS dissector could crash. This was addressed in epan/dissectors/packet-ldss.c by avoiding a buffer over-read upon encountering a missing '\0' character.
In Wireshark 2.6.0, the IEEE 802.11 protocol dissector could crash. This was addressed in epan/crypt/dot11decrypt.c by avoiding a buffer overflow during FTE processing in Dot11DecryptTDLSDeriveKey.
In Wireshark 2.6.0, 2.4.0 to 2.4.6, and 2.2.0 to 2.2.14, the GSM A DTAP dissector could crash. This was addressed in epan/dissectors/packet-gsm_a_dtap.c by fixing an off-by-one error that caused a buffer overflow.
In Wireshark 2.6.0, 2.4.0 to 2.4.6, and 2.2.0 to 2.2.14, the RRC dissector and other dissectors could crash. This was addressed in epan/proto.c by avoiding a NULL pointer dereference.
In Wireshark 2.6.0, 2.4.0 to 2.4.6, and 2.2.0 to 2.2.14, the Q.931 dissector could crash. This was addressed in epan/dissectors/packet-q931.c by avoiding a use-after-free after a malformed packet prevented certain cleanup.
In Wireshark 2.6.0, 2.4.0 to 2.4.6, and 2.2.0 to 2.2.14, the LTP dissector and other dissectors could consume excessive memory. This was addressed in epan/tvbuff.c by rejecting negative lengths.
