Mozilla Thunderbird < 60.5.1

high Nessus Plugin ID 122401

Language:

Synopsis

A mail client installed on the remote macOS or Mac OS X host is affected by multiple vulnerabilities.

Description

The version of Thunderbird installed on the remote macOS or Mac OS X host is prior to 60.5.1. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2019-06 advisory.

- A buffer overflow vulnerability in the Skia library can occur with Canvas 2D acceleration on macOS. This issue was addressed by disabling Canvas 2D acceleration in Firefox ESR. *Note: this does not affect other versions and platforms where Canvas 2D acceleration is already disabled by default. (CVE-2018-18335)

- A use-after-free vulnerability in the Skia library can occur when creating a path, leading to a potentially exploitable crash. (CVE-2018-18356)

- A flaw during verification of certain S/MIME signatures causes emails to be shown in Thunderbird as having a valid digital signature, even if the shown message contents aren't covered by the signature. The flaw allows an attacker to reuse a valid S/MIME signature to craft an email message with arbitrary content.
(CVE-2018-18509)

- An integer overflow vulnerability in the Skia library can occur after specific transform operations, leading to a potentially exploitable crash. (CVE-2019-5785)

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

Solution

Upgrade to Mozilla Thunderbird version 60.5.1 or later.
