Mozilla Thunderbird < 68.1 Multiple Vulnerabilities

High Nessus Plugin ID 128971

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 68.1. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2019-30 advisory, including the following:

- A use-after-free vulnerability can occur while manipulating video elements if the body is freed while still in use. This results in a potentially exploitable crash. (CVE-2019-11746)

- Some HTML elements, such as <title> and <textarea>, can contain literal angle brackets without treating them as markup. It is possible to pass a literal closing tag to .innerHTML on these elements, and subsequent content after that will be parsed as if it were outside the tag.
This can lead to XSS if a site does not filter user input as strictly for these elements as it does for other elements. (CVE-2019-11744)

- It is possible to delete an IndexedDB key value and subsequently try to extract it during conversion. This results in a use-after-free and a potentially exploitable crash. (CVE-2019-11752)

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 68.1 or later.
