Description
This security bulletin contains information about 12 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) Information disclosure (CVE-ID: CVE-2023-42884)
The vulnerability allows a local application to gain access to potentially sensitive information.
The vulnerability exists due to excessive data output in AVEVideoEncoder. A local application can read sensitive kernel memory.
3) Information disclosure (CVE-ID: CVE-2023-42922)
The vulnerability allows a local application to gain access to potentially sensitive information.
The vulnerability exists due to excessive data output by the Find My application. A local application can gain unauthorized access to sensitive information on the 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-2023-42883)
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.
7) 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.
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) Input validation error (CVE-ID: CVE-2023-42962)
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 CallKit. A remote attacker can trick the victim to click on a specially crafted link and crash the application.
10) Insecure Temporary File (CVE-ID: CVE-2023-42896)
The vulnerability allows a local application to escalate privileges on the system.
The vulnerability exists due to improper handling of temporary files in Assets. A local application can modify protected parts of the file system.
11) Race condition (CVE-ID: CVE-2023-42974)
The vulnerability allows a local application to escalate privileges on the system.
The vulnerability exists due to a race condition in IOUSBDeviceFamily. A local application can exploit the race and execute arbitrary code with kernel privileges.
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.
