Name of the Vulnerable Software and Affected Versions: Firefox versions prior to 125 Description: The issue is related to memory safety bugs present in Firefox, some of which showed evidence of memory corruption. It is presumed that with enough effort, some of these bugs could have been exploited to run arbitrary code. The vulnerability is also described as a buffer overflow in memory when processing HTML content, which could allow a remote attacker to execute arbitrary code. Recommendations: For versions prior to 125, update to version 125 or later to resolve the issue. As a temporary workaround, consider restricting access to potentially vulnerable HTML content until the update is applied.

A S/MIME issue existed in the handling of encrypted email, allowing an attacker to potentially recover plaintext contents of an S/MIME-encrypted email. This issue was addressed by not automatically loading some MIME parts.

The issue is related to the decryption of S/MIME parts in HTML messages, which can lead to plaintext leakage when included in a reply or forward. This is due to a lack of protection for certain data in the S/MIME and PGP functions of the Thunderbird email client. An attacker can exploit this issue by manipulating HTML messages to gain unauthorized access to protected information.

The issue is related to the Secure/Multipurpose Internet Mail Extensions (S/MIME) function in the Thunderbird email client, which lacks protection for certain data. This can allow a remote attacker to gain unauthorized access to protected information when an email is forwarded or replied to. Specifically, decrypted S/MIME parts that are hidden using CSS or the plaintext HTML tag can leak plaintext when included in an HTML reply or forward.

The issue involves the Security component and allows websites to track users by leveraging the transmission of S/MIME client certificates.

The issue involves the Mail component and allows remote attackers to read the cleartext content of S/MIME encrypted messages via direct exfiltration.

The issue is related to the implementation of the S/MIME protocol in the Thunderbird email client, which is associated with insufficiently robust data encryption. This can lead to the disclosure of plaintext when using remote content in encrypted messages. Exploitation of the issue may allow a remote attacker to gain unauthorized access to protected information.

The issue is related to information disclosure. It allows a remote attacker to gain unauthorized access to protected information through the `src` attribute of remote images or links. This could lead to the leakage of plaintext from decrypted emails.

The issue is related to the handling of encrypted emails in Thunderbird, where plaintext of decrypted emails can leak when a user submits an embedded form. This is due to a lack of encryption measures for protected data. Exploitation of this issue may allow a remote attacker to gain unauthorized access to protected information.

The issue involves the `Mail` component and allows man-in-the-middle attackers to read S/MIME encrypted message content. This is achieved by sending HTML e-mail that references remote resources but lacks a valid S/MIME signature.
