4) Security features bypass (CVE-ID: CVE-2023-25734)
The vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due to an error when handling Windows .url shortcuts that are opened by the browser from the local filesystem. A remote attacker can trick the victim into launching a specially crafted shortcut that then initiates network requests from the operating system to the malicious server. A remote attacker can obtain potentially sensitive information including NTLM credentials.

5) Out-of-bounds read (CVE-ID: CVE-2023-25738)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a missing validation of members of the DEVMODEW struct set by the printer device driver while printing web page in Windows. A remote attacker can trick the victim to print a specially crafted web page and crash the browser.
Note, the vulnerability affects Windows installations only.
