The netmonrec_comment_destroy function in wiretap/netmon.c in Wireshark through 2.4.4 performs a free operation on an uninitialized memory address, which allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact.

The remote Redhat Enterprise Linux 5 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)

  - Multiple integer overflows in Wireshark 1.4.x before 1.4.13 and 1.6.x before 1.6.8 allow remote attackers     to cause a denial of service (infinite loop) via vectors related to the (1) BACapp and (2) Bluetooth HCI     dissectors, a different vulnerability than CVE-2012-2392. (CVE-2012-3825)

  - The decompress_sigcomp_message function in epan/sigcomp-udvm.c in the SigComp UDVM dissector in Wireshark     1.10.x before 1.10.11 allows remote attackers to cause a denial of service (buffer over-read and     application crash) via a crafted packet. (CVE-2014-8710)

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 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.

The remote Redhat Enterprise Linux 8 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)

  - In Wireshark 2.4.0 to 2.4.3 and 2.2.0 to 2.2.11, the IxVeriWave file parser could crash. This was     addressed in wiretap/vwr.c by correcting the signature timestamp bounds checks. (CVE-2018-5334)

  - In Wireshark 2.4.0 to 2.4.3 and 2.2.0 to 2.2.11, the WCP dissector could crash. This was addressed in     epan/dissectors/packet-wcp.c by validating the available buffer length. (CVE-2018-5335)

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

This plugin has been deprecated as it does not adhere to established standards for this style of check.
