Description
This security bulletin contains information about 23 secuirty vulnerabilities.
1) Code Injection (CVE-ID: CVE-2022-2200)
The vulnerability allows a remote attacker to execute arbitrary JavaScript code.
The vulnerability exists due to improper input validation when handling JavaScript attributes. A remote attacker can pass undesired attributes to JavaScript object and perform prototype pollution and execute arbitrary JavaScript code in the browser.
2) Improper Verification of Cryptographic Signature (CVE-ID: CVE-2022-2226)
The vulnerability allows a remote attacker to perform spoofing attack.
The vulnerability exists due to improper validation of digital signatures. When displaying an email that contains a digital signature, the email's
date will be shown. If the dates were different, then Thunderbird didn't
report the email as having an invalid signature. If an attacker
performed a replay attack, in which an old email with old contents are
resent at a later time, it could lead the victim to believe that the
statements in the email are current.
3) Buffer overflow (CVE-ID: CVE-2022-2505)
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 web page, 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.
4) Security features bypass (CVE-ID: CVE-2022-3032)
The vulnerability allows a remote attacker to bypass implemented security restrictions.
The vulnerability exists doe to incorrect processing of HTML emails with an iframe</code> element that uses a <code>srcdoc attribute to define the inner HTML document. A remote attacker can trick the victim to open a specially crafted email message and bypass blocking of remote objects specified in the nested document, for example images or videos.
5) 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.
6) Security features bypass (CVE-ID: CVE-2022-3034)
The vulnerability allows a remote attacker to bypass implemented security restrictions.
The vulnerability exists due to iframe elements in an HTML email force the application to initiate network requests. A remote attacker can use an iframe to confirm that the email was read by the victim and obtain victim's IP address.
7) Security features bypass (CVE-ID: CVE-2022-31744)
The vulnerability allows a remote attacker to bypass implemented security restrictions.
The vulnerability exists due to an error when processing CSS stylesheets accessible via internal URIs, as "resource:". A remote attacker can bypass implemented Content Security Policy.
8) Security features bypass (CVE-ID: CVE-2022-34468)
The vulnerability allows a remote attacker to bypass implemented security restrictions.
The vulnerability exists due to improper handling of the CSP sandbox header without "allow-scripts" option. A remote attacker use an iframe to bypass implemented CSP restriction and execute scripts if the user clicks on a javascript: link.
9) Use-after-free (CVE-ID: CVE-2022-34470)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error in nsSHistory when handling XML documents. A remote attacker can 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.
10) Error Handling (CVE-ID: CVE-2022-34472)
The vulnerability allows a remote attacker to influence browser behavior.
The vulnerability exists due to improper error handling when processing unavailable PAC file. If a PAC URL is set and the server that hosts the PAC is unreachable, OCSP requests are blocked, resulting in incorrect error pages being shown.
11) Improper Authorization in Handler for Custom URL Scheme (CVE-ID: CVE-2022-34478)
The vulnerability allows a remote attacker to compromise the affected system.
The vulnerability exists due to insecure usage of URI handlers that allow usage of ms-msdt, search, and search-ms protocols. A remote attacker can trick the victim to click on a specially crafted link and execute arbitrary code on the system, if the victim accepts the browser prompt.
The vulnerability affects Firefox on Windows.
12) Improper Restriction of Rendered UI Layers or Frames (CVE-ID: CVE-2022-34479)
The vulnerability allows a remote attacker to perform spoofing attack.
The vulnerability exists due to improper handling of resizing event for a popup window. A remote attacker can create a specially crafted website that can create a resized popup to overlay the address bar with its own content and perform spoofing attack.
Note, the vulnerability affects Linux installations only.
13) Integer overflow (CVE-ID: CVE-2022-34481)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to integer overflow in the nsTArray_Impl::ReplaceElementsAt() function. A remote attacker can trick the victim to visit a specially crafted website, trigger an integer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
14) Buffer overflow (CVE-ID: CVE-2022-34484)
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.
15) Input validation error (CVE-ID: CVE-2022-36059)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied input in Matrix SDK. A remote attacker sharing a room with a victim can hide some of the rooms or spaces from users and cause minor temporary corruption.
16) Exposure of Resource to Wrong Sphere (CVE-ID: CVE-2022-36314)
The vulnerability allows an attacker to initiate unintended actions.
The vulnerability exists due to an error when opening .lnk shortcuts on the system. If the shortcut contains a link to an external resource the browser can initiate network requests from the operating system.
The vulnerability affects Windows installations only.
17) Cross-site scripting (CVE-ID: CVE-2022-36318)
The disclosed vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.
The vulnerability exists due to insufficient sanitization of user-supplied data when visiting directory listings for chrome:// URLs as source text. A remote attacker can execute arbitrary HTML and script code in user's browser in context of vulnerable website.

The vulnerability exists due to incorrect processing of XSLT errors. A remote attacker can spoof the address bar and trick the user into submitting data intended for the spoofed origin.
20) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2022-38473)
The vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due to incorrectly imposed security restrictions on a cross-origin iframe referencing an XSLT document. A remote attacker can trick the victim to visit a specially crafted website and inherit the parent domain's permissions to access microphone or camera.
21) Use-after-free (CVE-ID: CVE-2022-38476)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a data race within the in the PK11_ChangePW function. A remote attacker can trigger a use-after-free error and crash the browser.
