Description
This security bulletin contains information about 8 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) 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.
