This was addressed in epan/dissectors/packet-umts_mac.c by rejecting a certain reserved value. o 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. o 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. o 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. o 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. o 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. o 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. o 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. o 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. BIG-IQ, Enterprise Manager, F5 iWorkflow, ARX, LineRate, and Traffix SDC There is no impact; these F5 products are not affected by this vulnerability. Security Advisory Status F5 Product Development has assigned ID 710705 (BIG-IP) to this vulnerability. Additionally, BIG-IP iHealth may list Heuristic H34035645 on the Diagnostics > Identified > Medium page.

Security Advisory Recommended Actions If you are running a version listed in the Versions known to be vulnerable column, you can eliminate this vulnerability by upgrading to a version listed in the Fixes introduced in column. If the table lists only an older version than what you are currently running, or does not list a non-vulnerable version, then no upgrade candidate currently exists. Mitigation To mitigate this vulnerability, you can use the tshark utility to perform a traffic capture to a file instead of using the affected protocol parsers.
