In Wireshark 2.4.0, the Modbus dissector could crash with a NULL pointer dereference. This was addressed in epan/dissectors/packet-mbtcp.c by adding length validation.

The remote Redhat Enterprise Linux 6 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - wireshark: free operation on an uninitialized memory address in wiretap/netmon.c (CVE-2018-6836)

  - The dissector-table implementation in epan/packet.c in Wireshark 1.12.x before 1.12.7 mishandles table     searches for empty strings, which allows remote attackers to cause a denial of service (application crash)     via a crafted packet, related to the (1) dissector_get_string_handle and (2)     dissector_get_default_string_handle functions. (CVE-2015-6243)

  - The dissect_zbee_secure function in epan/dissectors/packet-zbee-security.c in the ZigBee dissector in     Wireshark 1.12.x before 1.12.7 improperly relies on length fields contained in packet data, which allows     remote attackers to cause a denial of service (application crash) via a crafted packet. (CVE-2015-6244)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

The remote Redhat Enterprise Linux 7 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - wireshark: free operation on an uninitialized memory address in wiretap/netmon.c (CVE-2018-6836)

  - The srtp_add_address function in epan/dissectors/packet-rtp.c in the RTP dissector in Wireshark 1.10.x     before 1.10.7 does not properly update SRTP conversation data, which allows remote attackers to cause a     denial of service (application crash) via a crafted packet. (CVE-2014-2907)

  - The dissect_frame function in epan/dissectors/packet-frame.c in the frame metadissector in Wireshark     1.10.x before 1.10.8 interprets a negative integer as a length value even though it was intended to     represent an error condition, which allows remote attackers to cause a denial of service (application     crash) via a crafted packet. (CVE-2014-4020)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

New version 2.4.2, fixes CVE-2017-15189, CVE-2017-15190, CVE-2017-15191, CVE-2017-15192, CVE-2017-15193, CVE-2017-13764, CVE-2017-13765, CVE-2017-13766, CVE-2017-13767

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora update system website.
Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The version of Wireshark installed on the remote Windows host is 2.4.x prior to 2.4.1. It is, therefore, affected by multiple denial of service vulnerabilities in the Modbus, IrCOMM, Profinet I/O, and MSDP dissectors. An unauthenticated, remote attacker can exploit this by injecting a malformed packet onto the wire or by convincing someone to read a malformed packet trace file.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
