Description
This security bulletin contains information about 19 secuirty vulnerabilities.
1) Input validation error (CVE-ID: CVE-2023-41992)
The vulnerability allows a local application to escalate privileges on the system.
The vulnerability exists due to insufficient validation of user-supplied input within the OS kernel. A local application can execute arbitrary code on the system with elevated privileges.
Note, the vulnerability is being actively exploited in the wild.
2) Improper Verification of Cryptographic Signature (CVE-ID: CVE-2023-41991)
The vulnerability allows a remote attacker application to bypass implemented security restrictions.
The vulnerability exists due to improper verification of cryptographic signature within the Security component. A remote attacker can create a specially crafted application that can bypass signature validation process, trick the victim into installing it and compromise the affected system.
Note, the vulnerability is being actively exploited in the wild.
3) Buffer overflow (CVE-ID: CVE-2023-41993)
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 in WebKit. 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.
Note, the vulnerability is being actively exploited in the wild.
4) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2023-35990)
The vulnerability allows a local application to gain access to sensitive information.
The vulnerability exists due to improperly imposed security restrictions in Safari. A local application can identify what other apps a user has installed.
5) Error Handling (CVE-ID: CVE-2023-40395)
The vulnerability allows a local application to gain access to sensitive information.

6) Out-of-bounds read (CVE-ID: CVE-2023-40403)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition in libxslt. A remote attacker can create a specially crafted website, trick the victim into opening it, trigger an out-of-bounds read error and read contents of memory on the system.
7) Buffer overflow (CVE-ID: CVE-2023-40420)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error in CoreAnimation. A remote attacker can trick the victim to visit a specially crafted website, trigger memory corruption and perform a denial of service (DoS) attack.
8) Security features bypass (CVE-ID: CVE-2023-40448)
The vulnerability allows a remote attacker to bypass implemented security restrictions.
The vulnerability exists due to improper input validation in App Store. A remote attacker can trick the victim to visit a specially crafted website and break out of Web Content sandbox.
9) Improper access control (CVE-ID: CVE-2023-40454)
The vulnerability allows a local application to delete arbitrary files on the system.
The vulnerability exists due to improper access restrictions in libxpc. A local application can delete arbitrary files on the system.
10) Buffer overflow (CVE-ID: CVE-2023-41063)
The vulnerability allows a local application to escalate privileges on the system.
The vulnerability exists due to a boundary error in Pro Res. A local application can trigger memory corruption and execute arbitrary code with kernel privileges.
11) Improper access control (CVE-ID: CVE-2023-41068)
The vulnerability allows a local application to escalate privileges on the system.
