7) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2024-27799)
The vulnerability allows a local application to log keystrokes in other apps.
The vulnerability exists due to improperly imposed security restrictions in IOHIDFamily. A local unprivileged application can log keystrokes in other apps including those using secure input mode.
8) Buffer overflow (CVE-ID: CVE-2024-27818)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error within the OS kernel. A remote attacker can trigger memory corruption and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
9) Security features bypass (CVE-ID: CVE-2024-27840)
The vulnerability allows a local user to bypass implemented security restrictions.
The vulnerability exists due to improper memory handling in the OS kernel. A local user who has already achieved kernel code execution can bypass kernel memory protections.
10) Improper Authentication (CVE-ID: CVE-2024-23251)
The vulnerability allows an attacker to gain access to sensitive information.
The vulnerability exists due to an error in Mail. An attacker with physical access to the system can leak Mail account credentials.
11) Improper Authorization (CVE-ID: CVE-2024-23282)
The vulnerability allows a remote attacker to initiate FaceTime calls.
The vulnerability exists due to improper input validation in Mail when processing email messages. A remote attacker can send a specially crafted email message, which can initiate FaceTime calls without user authorization.
12) Input validation error (CVE-ID: CVE-2024-27800)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied input in Messages. A remote attacker can send a specially crafted message to the application and crash it.
13) Out-of-bounds read (CVE-ID: CVE-2024-27802)
The vulnerability allows a remote attacker to compromise the affected system.
The vulnerability exists due to a boundary condition in Metal. A remote attacker can create a specially crafted file, trick the victim into opening it, trigger an out-of-bounds read error and read contents of memory on the system or execute arbitrary code.
14) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2024-27855)
The vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due to an error in Shortcuts. A remote attacker can trick the victim into clicking on a specially crafted shortcut and force it to use sensitive data with certain actions without prompting the user.
15) Information disclosure (CVE-ID: CVE-2024-27806)
The vulnerability allows a local application to gain access to potentially sensitive information.
The vulnerability exists due to improper environment sanitization in Spotlight. A local application can gain access to sensitive user data.
