Description
This security bulletin contains information about 12 secuirty vulnerabilities.
1) Buffer overflow (CVE-ID: CVE-2022-1919)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when processing webp images. A remote attacker can trick the victim into visiting a specially crafted webpage, 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) 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.3) 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.
4) 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.
5) 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.
6) 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.
7) 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.
8) Code Injection (CVE-ID: CVE-2022-31743)
The vulnerability allows a remote attacker to execute arbitrary JavaScript code.
The vulnerability exists due to improper input validation when handling HTML comment tags. A remote attacker can abuse this error to perform XSS attacks.
9) 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.

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to incorrect assertion when array shift operations are not used. The Garbage Collector can become confused about valid objects. This can lead to application crash.
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) Buffer overflow (CVE-ID: CVE-2022-31748)
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.
