The version of Wireshark installed on the remote Windows host is prior to 3.2.8. It is, therefore, affected by multiple vulnerabilities as referenced in the wireshark-3.2.8 advisory.
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)
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
