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.

  - 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.

Several issues in wireshark, a tool that captures and analyzes packets off the wire, have been found by different people. These are basically issues with length checks or invalid memory access in different dissectors. This could result in infinite loops or crashes by malicious packets.

For Debian 8 'Jessie', these problems have been fixed in version 1.12.1+g01b65bf-4+deb8u16.

We recommend that you upgrade your wireshark packages.

  - CVE-2016-7178: epan/dissectors/packet-umts_fp.c in the     UMTS FP dissector in Wireshark did not ensure that     memory is allocated for certain data structures, which     allowed remote attackers to cause a denial of service     (invalid write access and application crash) via a     crafted packet (bsc#998964).

  - CVE-2017-6014: In Wireshark a crafted or malformed     STANAG 4607 capture file will cause an infinite loop and     memory exhaustion. If the packet size field in a packet     header is null, the offset to read from will not     advance, causing continuous attempts to read the same     zero length packet. This will quickly exhaust all system     memory (bsc#1025913).

  - CVE-2017-5596: In Wireshark the ASTERIX dissector could     go into an infinite loop, triggered by packet injection     or a malformed capture file. This was addressed in     epan/dissectors/packet-asterix.c by changing a data type     to avoid an integer overflow (bsc#1021739).
