Description

This security bulletin contains information about 1 security vulnerability.


1) Information disclosure (CVE-ID: CVE-2022-45414)

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to the way quoted certain HTML tags are handled within the email client. If a Thunderbird user quoted from an HTML email, for example by replying to the email, and the email contained either a VIDEO tag with the POSTER attribute or an OBJECT tag with a DATA attribute, a network request to the referenced remote URL was performed, regardless of a configuration to block remote content. An image loaded from the POSTER attribute was shown in the composer window. A remote attacker trick the victim into replying to a specially crafted email and force Thunderbird to initiate requests, potentially revealing sensitive information, such as IP address of the victim.


Remediation

Install update from vendor's website.
