Security Bulletin

This security bulletin contains information about 7 vulnerabilities.

1) Spoofing attack

EUVDB-ID: #VU77002

Risk: Medium

CVSSv4.0: 1.2 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2023-34414

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 displaying certificate exceptions. The error page for sites with invalid TLS certificates was missing the activation-delay Firefox uses to protect prompts and permission dialogs from attacks that exploit human response time delays. If a malicious page elicited user clicks in precise locations immediately before navigating to a site with a certificate error and made the renderer extremely busy at the same time, it could create a gap between when the error page was loaded and when the display actually refreshed.

With the right timing the elicited clicks could land in that gap and activate the button that overrides the certificate error for that site.

Mitigation

Update the affected package thunderbird to the latest version.

Vulnerable software versions

Ubuntu: 20.04 - 23.04

thunderbird (Ubuntu package): before 1:102.13.0+build1-0ubuntu0.20.04.1
