Description
This security bulletin contains information about 17 secuirty vulnerabilities.
1) Out-of-bounds read (CVE-ID: CVE-2022-42854)
The vulnerability allows a local application to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition within the Bluetooth subsystem. A local application can trigger an out-of-bounds read error and read contents of memory on the system.
2) Buffer overflow (CVE-ID: CVE-2022-32942)
The vulnerability allows a local application to escalate privileges on the system.
The vulnerability exists due to a boundary error in DriverKit. A local application can trigger memory corruption and execute arbitrary code with kernel privileges.
3) Improper Privilege Management (CVE-ID: CVE-2022-42861)
The vulnerability allows a local application to bypass implemented security restrictions.
The vulnerability exists due to improper privilege management in macOS kernel. A local application can break out of its sandbox.
4) Race condition (CVE-ID: CVE-2022-42864)
The vulnerability allows a local application to escalate privileges on the system.
The vulnerability exists due to a race condition in IOHIDFamily. A local application can exploit the race and execute arbitrary code with kernel privileges.
5) Race condition (CVE-ID: CVE-2022-46689)
The vulnerability allows a local application to escalate privileges on the system.
The vulnerability exists due to a race condition in macOS kernel. A local application can exploit the race and execute arbitrary code with kernel privileges.
6) Buffer overflow (CVE-ID: CVE-2022-42845)
The vulnerability allows a local application to escalate privileges on the system.
7) Buffer overflow (CVE-ID: CVE-2022-42842)
The vulnerability allows a local application to escalate privileges on the system.
The vulnerability exists due to a boundary error in macOS kernel. A local application can trigger memory corruption and execute arbitrary code with kernel privileges.
8) Integer overflow (CVE-ID: CVE-2022-40303)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to integer overflow in parse.c when processing content when XML_PARSE_HUGE is set. A remote attacker can pass specially crafted data to the application, trigger an integer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
9) Resource management error (CVE-ID: CVE-2022-40304)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists in entities.c due to the way libxml2 handles reference cycles. The library does not anticipate that entity content can be allocated from a dict and clears it upon reference cycle detection by setting its first byte to zero. This can lead to memory corruption issues, such as double free errors and result in a denial of service.
10) Buffer overflow (CVE-ID: CVE-2022-42840)
The vulnerability allows a local application to escalate privileges on the system.
The vulnerability exists due to a boundary error in ppp component. A local application can trigger memory corruption and execute arbitrary code with kernel privileges.
11) State Issues (CVE-ID: CVE-2022-42855)
The vulnerability allows a local application to gain access to bypass certain security restrictions.
The vulnerability exists due to a state management issue within the Preferences component. A local application can use arbitrary entitlements.
12) Type Confusion (CVE-ID: CVE-2022-42841)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a type confusion error in xar when processing specially crafted packages. A remote attacker can trick the victim to open a specially crafted package, trigger a type confusion error and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
13) Security features bypass (CVE-ID: CVE-2022-42821)
The vulnerability allows a local application to bypass implemented security restrictions.
The vulnerability exists due to a logic error in BOM component. A local application can bypass Gatekeeper checks.
14) Improper Privilege Management (CVE-ID: CVE-2022-46704)
The vulnerability allows a local application to bypass implemented security restrictions.
The vulnerability exists due to a logic issue in the PackageKit component. A local application can modify protected parts of the file system.
15) Improper Privilege Management (CVE-ID: CVE-2022-42853)
The vulnerability allows a local application to modify protected parts of the file system.
The vulnerability exists due to improper privilege management in Boot Camp. A local application can modify protected parts of the file system.
16) Information disclosure (CVE-ID: CVE-2022-46703)
The vulnerability allows a local application to gain access to potentially sensitive information.
The vulnerability exists due to a logic error in the Weather feature. A local application can obtain sensitive location information.
17) Information disclosure (CVE-ID: CVE-2022-46718)
The vulnerability allows a local application to gain access to potentially sensitive information.
The vulnerability exists due to excessive data output in TCC. A local application can gain unauthorized access to sensitive information on the system.
