Amazon Linux 2 : thunderbird (ALAS-2020-1496)

high Nessus Plugin ID 141108

Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

The version of thunderbird installed on the remote host is prior to 68.12.0-1. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2020-1496 advisory.

By holding a reference to the eval() function from an about:blank window, a malicious webpage could have gained access to the InstallTrigger object which would allow them to prompt the user to install an extension. Combined with user confusion, this could result in an unintended or malicious extension being installed. (cve-2020-15664)See: https://www.mozilla.org/en- US/security/advisories/mfsa2020-40/#CVE%2D2020%2D15664

When aborting an operation, such as a fetch, an abort signal may be deleted while alerting the objects to be notified. This results in a use-after-free and we presume that with enough effort it could have been exploited to run arbitrary code. (cve-2020-15669)See: https://www.mozilla.org/en- US/security/advisories/mfsa2020-40/#CVE%2D2020%2D15669

Tenable has extracted the preceding description block directly from the tested product security advisory.

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

Solution

Run 'yum update thunderbird' to update your system.
