Wireshark 2.2.x < 2.2.13 Multiple Vulnerabilities (macOS)

high Nessus Plugin ID 311415

Synopsis

An application installed on the remote macOS / Mac OS X host is affected by multiple vulnerabilities.

Description

The version of Wireshark installed on the remote macOS / Mac OS X host is prior to 2.2.13. It is, therefore, affected by multiple vulnerabilities as referenced in the wireshark-2.2.13 advisory.

- In Wireshark 2.2.0 to 2.2.12 and 2.4.0 to 2.4.4, the pcapng file parser could crash. This was addressed in wiretap/pcapng.c by adding a block-size check for sysdig event blocks. (CVE-2018-7420)

- In Wireshark 2.4.0 to 2.4.4 and 2.2.0 to 2.2.12, the IEEE 802.11 dissector could crash. This was addressed in epan/crypt/airpdcap.c by rejecting lengths that are too small. (CVE-2018-7335)

- In Wireshark 2.4.0 to 2.4.4 and 2.2.0 to 2.2.12, epan/dissectors/packet-thrift.c had a large loop that was addressed by not proceeding with dissection after encountering an unexpected type. (CVE-2018-7321)

- In Wireshark 2.4.0 to 2.4.4 and 2.2.0 to 2.2.12, epan/dissectors/packet-dcm.c had an infinite loop that was addressed by checking for integer wraparound. (CVE-2018-7322)

- In Wireshark 2.4.0 to 2.4.4 and 2.2.0 to 2.2.12, epan/dissectors/packet-wccp.c had a large loop that was addressed by ensuring that a calculated length was monotonically increasing. (CVE-2018-7323)

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 2.2.13 or later.
