Mozilla Thunderbird < 60.7.2

critical Nessus Plugin ID 126218
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

A mail client installed on the remote Windows host is affected by multiple vulnerabilities.

Description

The version of Thunderbird installed on the remote Windows host is prior to 60.7.2. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2019-20 advisory.

- A denial of service (DoS) vulnerability exists in the Arrays.pop component due to a type confusion vulnerability. An unauthenticated, remote attacker can exploit this issue, by manipulating JavaScript objects, to cause the application to stop responding (CVE-2019-11707).

- A remote command execution vulnerability exists in Thunderbird's Prompt:Open IPC component due to insufficient validation of user-supplied data. An unauthenticated, remote attacker can exploit this to escape a child process' sandbox and execute arbitrary commands with the priviliges of the user running the main Thunderbird process (CVE-2019-11708).

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 60.7.2 or later.
