Description

This security bulletin contains information about 12 secuirty vulnerabilities.


1) Insufficient UI Warning of Dangerous Operations (CVE-ID: CVE-2023-4051)

The vulnerability allows a remote attacker to perform spoofing attack.

The vulnerability exists due to an error when displaying the full screen notification by using the file open dialog. A remote attacker can trick the victim into clocking on the file open dialog and perform spoofing attack.


2) Insufficient UI Warning of Dangerous Operations (CVE-ID: CVE-2023-4053)

The vulnerability allows a remote attacker to perform spoofing attack.

The vulnerability exists due an error when handling full screen notifications. A malicious website can obscure the full screen notification by using a URL with a scheme handled by an external program, such as a mailto URL, and perform spoofing attack.


3) Use-after-free (CVE-ID: CVE-2023-4573)

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a use-after-free error in IPC CanvasTranslator. A remote attacker can trick the victim to open a specially crafted website, trigger memory corruption and execute arbitrary code on the system.

Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.


4) Use-after-free (CVE-ID: CVE-2023-4574)

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a use-after-free error in IPC ColorPickerShownCallback. A remote attacker can trick the victim to open a specially crafted website, trigger memory corruption and execute arbitrary code on the system.

Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.


5) Use-after-free (CVE-ID: CVE-2023-4575)

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a use-after-free error in IPC FilePickerShownCallback. A remote attacker can trick the victim to open a specially crafted website, trigger memory corruption and execute arbitrary code on the system.

Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.


6) Buffer overflow (CVE-ID: CVE-2023-4577)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error in JIT UpdateRegExpStatics when UpdateRegExpStatics attempted to access initialStringHeap. 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.


7) Resource exhaustion (CVE-ID: CVE-2023-4578)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to application does not properly control consumption of internal resources in JS::CheckRegExpSyntax. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.


8) Cleartext storage of sensitive information (CVE-ID: CVE-2023-4580)

The vulnerability allows a local user to gain access to sensitive information.
