Description
This security bulletin contains information about 17 secuirty vulnerabilities.
1) Security features bypass (CVE-ID: CVE-2022-42927)
The vulnerability allows a remote attacker to bypass implemented security restrictions.
The vulnerability exists due to same-origin policy violation in the performance.getEntries() method. A remote attacker can trick the victim to open a specially crafted website and gain obtain cross-origin URL entries.
2) Buffer overflow (CVE-ID: CVE-2022-42928)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error in Garbage Collector within the JS engine. 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.
3) Resource management error (CVE-ID: CVE-2022-42929)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to improper management of internal resources within the application when handling window.print() events. A remote attacker trick the victim to open a specially crafted website and perform a denial of service (DoS) attack.
4) Buffer overflow (CVE-ID: CVE-2022-42932)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when handling 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.
5) Information disclosure (CVE-ID: CVE-2022-45403)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to an error in Service Workers. A remote attacker can obtain information about the presence or length of a media file using timing information for cross-origin media combined with Range requests.
6) Spoofing attack (CVE-ID: CVE-2022-45404)
The vulnerability allows a remote attacker to perform spoofing attack.
The vulnerability exists due to incorrect processing of a series of popup and window.print() calls. A remote attacker can force the browser to go fullscreen without the user seeing the notification prompt, resulting in potential user confusion or spoofing attacks.
7) Use-after-free (CVE-ID: CVE-2022-45405)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error within the InputStream implementation. A remote attacker can trick the victim to visit 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.
8) Use-after-free (CVE-ID: CVE-2022-45406)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error when handling JavaScript realms. A remote attacker can trick the victim to visit 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.
9) Spoofing attack (CVE-ID: CVE-2022-45408)
The vulnerability allows a remote attacker to perform spoofing attack.
The vulnerability exists due to incorrect processing of a series of popups that reuse windowName. A remote attacker can force the browser to go fullscreen without the user seeing the notification prompt, resulting in potential user confusion or spoofing attacks.
10) Use-after-free (CVE-ID: CVE-2022-45409)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error in Garbage Collection. A remote attacker can trick the victim to visit 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.
11) Security features bypass (CVE-ID: CVE-2022-45410)
The vulnerability allows a remote attacker to bypass implemented security restrictions.
The vulnerability exists due to an error when handling ServiceWorker-intercepted requests. When a ServiceWorker intercepted a request with FetchEvent, the origin of the request was lost after the ServiceWorker took ownership of it. This had the effect of negating SameSite cookie protections.
12) Cross-site tracing (CVE-ID: CVE-2022-45411)
The vulnerability allows a remote attacker to bypass implemented security restrictions.
The vulnerability exists due to an error when handling non-standard headers. Cross-Site Tracing occurs when a server will echo a request back via the Trace method, allowing an XSS attack to access to authorization headers and cookies inaccessible to JavaScript (such as cookies protected by HTTPOnly). To mitigate this attack, browsers placed limits on fetch() and XMLHttpRequest; however some webservers have implemented non-standard headers such as X-Http-Method-Override
that override the HTTP method, and made this attack possible again.
13) Out-of-bounds read (CVE-ID: CVE-2022-45412)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition when resolving a symlink such as file:///proc/self/fd/1. A remote attacker can create a specially crafted website, trick the victim into opening it, trigger out-of-bounds read error and read contents of unitialized memory via an error message.
Note, this vulnerability does not affect Windows installations.
14) Security features bypass (CVE-ID: CVE-2022-45416)
The vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due to keystroke side-channel leakage. Keyboard events reference strings like "KeyA" that were at fixed, known, and widely-spread addresses. Cache-based timing attacks such as Prime+Probe could have possibly figured out which keys were being pressed.
15) Spoofing attack (CVE-ID: CVE-2022-45418)
The vulnerability allows a remote attacker to perform spoofing attack.
The vulnerability exists due to incorrect processing of custom mouse cursor. A remote attacker can draw a custom mouse cursor, specified in CSS, over the browser UI, resulting in potential user confusion or spoofing attacks.
16) Spoofing attack (CVE-ID: CVE-2022-45420)
The vulnerability allows a remote attacker to perform spoofing attack.
The vulnerability exists due to incorrect processing of tables inside of an iframe. A remote attacker can cause iframe contents to be rendered outside the boundaries of the iframe, resulting in potential user confusion or spoofing attacks.
17) Buffer overflow (CVE-ID: CVE-2022-45421)
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.
