Description
This security bulletin contains information about 11 secuirty vulnerabilities.
1) Use-after-free (CVE-ID: CVE-2022-22624)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error when processing HTML content in WebKit. 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.
2) Use-after-free (CVE-ID: CVE-2022-22628)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error when processing HTML content in WebKit. 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.
3) Heap-based buffer overflow (CVE-ID: CVE-2022-22629)
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 within the WebGLMultiDraw component. A remote attacker can create a specially crafted web page, trick the victim into opening it, trigger a heap-based buffer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
4) Information disclosure (CVE-ID: CVE-2022-22662)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a cookie management issue in WebKit. A remote attacker can trick the victim to open a specially crafted webpage and gain access to sensitive information.
