    packet injection or crafted capture file. (CVE-2020-26418)

  - In Wireshark through 3.2.7, the Facebook Zero Protocol (aka FBZERO) dissector could enter an infinite
    loop. This was addressed in epan/dissectors/packet-fbzero.c by correcting the implementation of offset
    advancement. (CVE-2020-26575)

  - In Wireshark 3.2.0 to 3.2.7, the GQUIC dissector could crash. This was addressed in
    epan/dissectors/packet-gquic.c by correcting the implementation of offset advancement. (CVE-2020-28030)

    packet injection or crafted capture file (CVE-2021-4185)

  - Due to a failure in validating the length provided by an attacker-crafted CP2179 packet, Wireshark
    versions 2.0.0 through 4.0.7 is susceptible to a divide by zero allowing for a denial of service attack.
