Description

This security bulletin contains information about 17 secuirty vulnerabilities.


1) Spoofing attack (CVE-ID: CVE-2022-1834)

The vulnerability allows a remote attacker to perform spoofing attack.

The vulnerability exists due to incorrect processing of multiple Braille Pattern Blank space characters, which results in displaying every space character. A remote attacker can spoof the email address of the sender.


2) 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.


3) 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.


4) Information disclosure (CVE-ID: CVE-2022-31736)

The vulnerability allows a remote attacker to bypass implemented security restrictions.

The vulnerability exists due to an error when processing HTTP requests. A malicious website can obtain the size of a cross-origin resource that supported Range requests.

5) Out-of-bounds write (CVE-ID: CVE-2022-31737)

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a boundary error in WebGL when processing HTML content. A remote attacker can create a specially crafted website, trick the victim into opening it using the affected software, trigger out-of-bounds write and execute arbitrary code on the target system.


6) Spoofing attack (CVE-ID: CVE-2022-31738)

The vulnerability allows a remote attacker to perform spoofing attack.

The vulnerability exists due to an error when exiting fullscreen mode. A remote attacker can use an iframe to confused the browser about the current state of fullscreen and perform spoofing attack.


7) Buffer overflow (CVE-ID: CVE-2022-31740)

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

The vulnerability exists due to a boundary error related to register allocation problem in WASM on arm64. A remote attacker can create a specially crafted webpage, 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.


8) Use of Uninitialized Variable (CVE-ID: CVE-2022-31741)

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 webpage, 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.


9) Information disclosure (CVE-ID: CVE-2022-31742)

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

The vulnerability exists due to an error when handling a large number of allowCredential entries. A remote attacker can trick the victim to visit a specially crafted website, launch a timing attack and detect the difference between invalid key handles and cross-origin key handles. Successful exploitation of the vulnerability can lead to cross-origin account linking in violation of WebAuthn goals.


10) 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.


11) Buffer overflow (CVE-ID: CVE-2022-31747)

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.


12) 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.


13) 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.


14) 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.


15) 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.


16) 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.


17) 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.
