Ubuntu update for thunderbird

1) Spoofing attack

EUVDB-ID: #VU62808

Risk: Low

CVSSv3.1: 2.7 [CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:N/I:L/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-1520

CWE-ID: CWE-451 - User Interface (UI) Misrepresentation of Critical Information (Clickjacking, spoofing)

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform spoofing attack.

The vulnerability exists due to incorrect processing of user-supplied data when processing signed and encrypted attached messages. If an email contains 2 attached messages, Thunderbird displays security status of the first opened attached message for the second attached message. As a result an attacker can spoof security status of the second attached message.
