Synopsis

An application installed on the remote Windows host is affected by multiple vulnerabilities.

Description

The version of Wireshark installed on the remote Windows host is prior to 2.6.2. It is, therefore, affected by multiple vulnerabilities as referenced in the wireshark-2.6.2 advisory.

- In Wireshark 2.6.0 to 2.6.1, 2.4.0 to 2.4.7, and 2.2.0 to 2.2.15, the HTTP2 dissector could crash. This was addressed in epan/dissectors/packet-http2.c by verifying that header data was found before proceeding to header decompression. (CVE-2018-14369)

- In Wireshark 2.6.0 to 2.6.1, 2.4.0 to 2.4.7, and 2.2.0 to 2.2.15, the Bazaar protocol dissector could go into an infinite loop. This was addressed in epan/dissectors/packet-bzr.c by properly handling items that are too long. (CVE-2018-14368)

- In Wireshark 2.6.0 to 2.6.1, 2.4.0 to 2.4.7, and 2.2.0 to 2.2.15, the BGP protocol dissector could go into a large loop. This was addressed in epan/dissectors/packet-bgp.c by validating Path Attribute lengths.
(CVE-2018-14342)

- In Wireshark 2.6.0 to 2.6.1, 2.4.0 to 2.4.7, and 2.2.0 to 2.2.15, the ISMP dissector could crash. This was addressed in epan/dissectors/packet-ismp.c by validating the IPX address length to avoid a buffer over- read. (CVE-2018-14344)

- In Wireshark 2.6.0 to 2.6.1, 2.4.0 to 2.4.7, and 2.2.0 to 2.2.15, dissectors that support zlib decompression could crash. This was addressed in epan/tvbuff_zlib.c by rejecting negative lengths to avoid a buffer over-read. (CVE-2018-14340)

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

Solution

Upgrade to Wireshark version 2.6.2 or later.
