Description
This security bulletin contains information about 12 secuirty vulnerabilities.
1) 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.
2) 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.
3) 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.
4) 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.
5) 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.
6) 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.
Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.
7) Spoofing attack (CVE-ID: CVE-2022-36319)
The vulnerability allows a remote attacker to perform spoofing attack.
The vulnerability exists due to an error, related to mouse pointer positioning when combining CSS properties for overflow and transform. A remote attacker can trick the victim into interacting with mouse cursor with different coordinates than displayed.
8) Spoofing attack (CVE-ID: CVE-2022-38472)
The vulnerability allows a remote attacker to perform spoofing attack.
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.
9) 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.
10) 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.
11) Buffer overflow (CVE-ID: CVE-2022-38477)
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) Buffer overflow (CVE-ID: CVE-2022-38478)
