Description
This security bulletin contains information about 11 secuirty vulnerabilities.
1) Type Confusion (CVE-ID: CVE-2023-4068)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a type confusion error within the V8 component in Google Chrome. A remote attacker can create a specially crafted web page, trick the victim into visiting it, trigger a type confusion error and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
2) Type Confusion (CVE-ID: CVE-2023-4069)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a type confusion error within the V8 component in Google Chrome. A remote attacker can create a specially crafted web page, trick the victim into visiting it, trigger a type confusion error and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
3) Type Confusion (CVE-ID: CVE-2023-4070)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a type confusion error within the V8 component in Google Chrome. A remote attacker can create a specially crafted web page, trick the victim into visiting it, trigger a type confusion error and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
4) Heap-based buffer overflow (CVE-ID: CVE-2023-4071)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a boundary error when processing untrusted HTML content in Visuals. 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.
5) Out-of-bounds write (CVE-ID: CVE-2023-4072)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a boundary error in WebGL in Google Chrome. A remote attacker can create a specially crafted website, trick the victim into opening it, trigger an out-of-bounds write and execute arbitrary code on the target system.
6) Buffer overflow (CVE-ID: CVE-2023-4073)
The vulnerability allows a remote attacker to compromise the affected system.
The vulnerability exists due to a boundary error in ANGLE in Google Chrome. A remote attacker can trick the victim to visit a specially crafted webpage, trigger a stack-based buffer overflow and execute arbitrary code on the system.
