Description
This security bulletin contains information about 16 secuirty vulnerabilities.
1) Inclusion of Sensitive Information in Log Files (CVE-ID: CVE-2023-42919)
The vulnerability allows a local application to gain access to sensitive information.
The vulnerability exists due to the Accounts component stores sensitive information into log files. A local application can read the log files and gain access to sensitive data.
2) Inclusion of Sensitive Information in Log Files (CVE-ID: CVE-2023-42927)
The vulnerability allows a local application to gain access to sensitive information.
The vulnerability exists due to ExtensionKit stores sensitive information into log files. A local application can read the log files and gain access to sensitive data.
3) Buffer overflow (CVE-ID: CVE-2023-42898)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error within the ImageIO component. A remote attacker can create a specially crafted image file, 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.
4) Buffer overflow (CVE-ID: CVE-2023-42899)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error within the ImageIO component. A remote attacker can create a specially crafted image file, 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.
5) Buffer overflow (CVE-ID: CVE-2023-42914)
The vulnerability allows a local application to bypass sandbox restrictions.
The vulnerability exists due to a boundary error within the OS kernel. A local application can break out of its sandbox.
6) Buffer overflow (CVE-ID: CVE-2023-42890)
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.
7) Buffer overflow (CVE-ID: CVE-2023-42883)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
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 crash the application.
8) Out-of-bounds read (CVE-ID: CVE-2023-42916)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a boundary error when processing untrusted input. A remote attacker can create a specially crafted website, trick the victim into opening it, trigger an out-of-bounds read and execute arbitrary code on the target system.
Note, the vulnerability is being actively exploited in the wild.
9) Buffer overflow (CVE-ID: CVE-2023-42917)
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. 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.
10) Inclusion of Sensitive Information in Log Files (CVE-ID: CVE-2023-42937)
The vulnerability allows a local application to gain access to sensitive information.
The vulnerability exists due to the Accessibility feature stores sensitive information into log files. A local application can read the log files and gain access to sensitive user data.
11) Out-of-bounds read (CVE-ID: CVE-2023-42888)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition in ImageIO. A remote attacker can create a specially crafted MPO image, trick the victim into opening it, trigger an out-of-bounds read error and read contents of memory on the system.
12) Improper access control (CVE-ID: CVE-2023-42893)
The vulnerability allows a local application to gain access to sensitive information.
The vulnerability exists due to improper access restrictions in Libsystem. A local application can access protected user data.
13) Information disclosure (CVE-ID: CVE-2023-42936)
The vulnerability allows a local application to gain access to potentially sensitive information.
The vulnerability exists due to excessive data output in Sandbox. A local application can gain unauthorized access to sensitive user information.
14) Path traversal (CVE-ID: CVE-2023-42947)
The vulnerability allows a local application to bypass implemented security restrictions.
The vulnerability exists due to input validation error when processing file paths in TCC. A local application can break out of its sandbox.
15) Use-after-free (CVE-ID: CVE-2023-42950)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error when processing HTML content in WebKit. A remote attacker can trick the victim to visit a specially crafted website, trigger a use-after-free error and execute arbitrary code on the system.
Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.
16) Information disclosure (CVE-ID: CVE-2023-40389)
The vulnerability allows a local application to gain access to potentially sensitive information.
The vulnerability exists due to excessive data output by Transparency. A local application can gain unauthorized access to sensitive user information.
