Description

This security bulletin contains information about 8 secuirty vulnerabilities.


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.


2) Information disclosure (CVE-ID: CVE-2022-3033)

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

The vulnerability exists due to the way Thunderbird handles the meta tag having the http-equiv="refresh" attribute in email messages when the user replies to an email. A remote attacker can send a specially crafted email to the victim and force the application to initiate requests to an external URL regardless of the configuration to block remote content.

Combined with other HTML elements and attributes in the email, it is possible to execute arbitrary JavaScript code included into the malicious message in the context of the message compose document and read or modify the contents of the message compose document, including the quoted original message, which could potentially contain the decrypted plaintext of encrypted data in the crafted email.



3) Security features bypass (CVE-ID: CVE-2022-46872)

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

The vulnerability exists due to unspecified error on Linux installations. A remote attacker who compromised content process can escaped the sandbox and read arbitrary files via clipboard-related IPC messages.


4) Input validation error (CVE-ID: CVE-2022-46874)

The vulnerability allows a remote attacker to perform a spoofing attack.

The vulnerability exists due to insufficient validation of long filenames during drag and drop actions, which causes filename truncation to a potentially malicious extension. A remote attacker can trick the victim to download a file with a long filename, which can be automatically truncated by the browser into an executable file.


5) Buffer overflow (CVE-ID: CVE-2022-46878)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error when processing HTML content. A remote attacker can create a specially crafted website, trick the victim into opening it, trigger memory corruption and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.


6) Use-after-free (CVE-ID: CVE-2022-46880)

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a use-after-free error in WebGL. A remote attacker can trick the victim to open a specially crafted website, trigger a use-after-free error and execute arbitrary code on the system.

Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.


7) Buffer overflow (CVE-ID: CVE-2022-46881)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error in WebGL. A remote attacker can trick the victim into opening a specially crafted website, trigger memory corruption and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.


8) Use-after-free (CVE-ID: CVE-2022-46882)

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a use-after-free error in WebGL. A remote attacker can trick the victim to open a specially crafted website, trigger a use-after-free error and execute arbitrary code on the system.

Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.
