"CVE-2018-7320

In Wireshark 2.4.0 to 2.4.4 and 2.2.0 to 2.2.12, the SIGCOMP protocol
dissector could crash. This was addressed in
epan/dissectors/packet-sigcomp.c by validating operand offsets.

CVE-2018-7321 In Wireshark 2.4.0 to 2.4.4 and 2.2.0 to 2.2.12,
epan/dissectors/packet-thrift.c had a large loop that was addressed by
not proceeding with dissection after encountering an unexpected type.

CVE-2018-7322 In Wireshark 2.4.0 to 2.4.4 and 2.2.0 to 2.2.12,
epan/dissectors/packet-dcm.c had an infinite loop that was addressed
by checking for integer wraparound.

CVE-2018-7323 In Wireshark 2.4.0 to 2.4.4 and 2.2.0 to 2.2.12,
epan/dissectors/packet-wccp.c had a large loop that was addressed by
ensuring that a calculated length was monotonically increasing.

CVE-2018-7324 In Wireshark 2.4.0 to 2.4.4 and 2.2.0 to 2.2.12,
epan/dissectors/packet-sccp.c had an infinite loop that was addressed
by using a correct integer data type.

CVE-2018-7325 In Wireshark 2.4.0 to 2.4.4 and 2.2.0 to 2.2.12,
epan/dissectors/packet-rpki-rtr.c had an infinite loop that was
addressed by validating a length field.

CVE-2018-7326 In Wireshark 2.4.0 to 2.4.4 and 2.2.0 to 2.2.12,
epan/dissectors/packet-lltd.c had an infinite loop that was addressed
by using a correct integer data type.

CVE-2018-7327 In Wireshark 2.4.0 to 2.4.4 and 2.2.0 to 2.2.12,
epan/dissectors/packet-openflow_v6.c had an infinite loop that was
addressed by validating property lengths.

CVE-2018-7328 In Wireshark 2.4.0 to 2.4.4 and 2.2.0 to 2.2.12,
epan/dissectors/packet-usb.c had an infinite loop that was addressed
by rejecting short frame header lengths.

CVE-2018-7329 In Wireshark 2.4.0 to 2.4.4 and 2.2.0 to 2.2.12,
epan/dissectors/packet-s7comm.c had an infinite loop that was
addressed by correcting off-by-one errors.

CVE-2018-7330 In Wireshark 2.4.0 to 2.4.4 and 2.2.0 to 2.2.12,
epan/dissectors/packet-thread.c had an infinite loop that was
addressed by using a correct integer data type.

CVE-2018-7331 In Wireshark 2.4.0 to 2.4.4 and 2.2.0 to 2.2.12,
epan/dissectors/packet-ber.c had an infinite loop that was addressed
by validating a length.

CVE-2018-7332 In Wireshark 2.4.0 to 2.4.4 and 2.2.0 to 2.2.12,
epan/dissectors/packet-reload.c had an infinite loop that was
addressed by validating a length.

CVE-2018-7333 In Wireshark 2.4.0 to 2.4.4 and 2.2.0 to 2.2.12,
epan/dissectors/packet-rpcrdma.c had an infinite loop that was
addressed by validating a chunk size.

CVE-2018-7334 In Wireshark 2.4.0 to 2.4.4 and 2.2.0 to 2.2.12, the
UMTS MAC dissector could crash. This was addressed in
epan/dissectors/packet-umts_mac.c by rejecting a certain reserved
value.

CVE-2018-7335 In Wireshark 2.4.0 to 2.4.4 and 2.2.0 to 2.2.12, the
IEEE 802.11 dissector could crash. This was addressed in
epan/crypt/airpdcap.c by rejecting lengths that are too small.

CVE-2018-7336 In Wireshark 2.4.0 to 2.4.4 and 2.2.0 to 2.2.12, the FCP
protocol dissector could crash. This was addressed in
epan/dissectors/packet-fcp.c by checking for a NULL pointer.

CVE-2018-7337 In Wireshark 2.4.0 to 2.4.4, the DOCSIS protocol
dissector could crash. This was addressed in
plugins/docsis/packet-docsis.c by removing the recursive algorithm
that had been used for concatenated PDUs.

CVE-2018-7417 In Wireshark 2.2.0 to 2.2.12 and 2.4.0 to 2.4.4, the
IPMI dissector could crash. This was addressed in
epan/dissectors/packet-ipmi-picmg.c by adding support for crafted
packets that lack an IPMI header.

CVE-2018-7418 In Wireshark 2.2.0 to 2.2.12 and 2.4.0 to 2.4.4, the
SIGCOMP dissector could crash. This was addressed in
epan/dissectors/packet-sigcomp.c by correcting the extraction of the
length value.

CVE-2018-7419 In Wireshark 2.2.0 to 2.2.12 and 2.4.0 to 2.4.4, the
NBAP dissector could crash. This was addressed in
epan/dissectors/asn1/nbap/nbap.cnf by ensuring DCH ID initialization.

CVE-2018-7420 In Wireshark 2.2.0 to 2.2.12 and 2.4.0 to 2.4.4, the
pcapng file parser could crash. This was addressed in wiretap/pcapng.c
by adding a block-size check for sysdig event blocks.

CVE-2018-7421 In Wireshark 2.2.0 to 2.2.12 and 2.4.0 to 2.4.4, the DMP
dissector could go into an infinite loop. This was addressed in
epan/dissectors/packet-dmp.c by correctly supporting a bounded number
of Security Categories for a DMP Security Classification.

Impact

BIG-IP

A remote attacker can transmit crafted packets while a BIG-IP
administrator account runs the tshark utility with the affected
protocol parsers via Advanced Shell ( bash ). This causes the tshark
utility to stop responding and may allow remote code execution from
the BIG-IP administrator account.
