Description

This security bulletin contains information about 21 secuirty vulnerabilities.


1) 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.


2) Type Confusion (CVE-ID: CVE-2022-42856)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a type confusion error in WebKit. A remote attacker can trick the victim to visit a specially crafted website, 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.

Note, the vulnerability is being actively exploited in the wild.


3) Buffer overflow (CVE-ID: CVE-2022-46700)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error in WebKit when processing HTML content. A remote attacker can create a specially crafted web page, 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) Security features bypass (CVE-ID: CVE-2022-46692)

The vulnerability allows a remote attacker to bypass implemented security restrictions.

The vulnerability exists due to a logic issue in WebKit. A remote attacker can trick the victim to visit a specially crafted web page and bypass Same Origin Policy.


5) Out-of-bounds read (CVE-ID: CVE-2022-42852)

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to a boundary condition in WebKit. A remote attacker can trick the victim to visit a specially crafted web page, trigger an out-of-bounds read error and read contents of memory on the system.


6) Buffer overflow (CVE-ID: CVE-2022-46691)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error in WebKit when processing HTML content. A remote attacker can create a specially crafted web page, trick the victim into opening it, trigger memory corruption and execute arbitrary code on the target system.


7) Spoofing attack (CVE-ID: CVE-2022-46695)

The vulnerability allows a remote attacker to perform spoofing attack.

The vulnerability exists due to incorrect processing of URLs in Safari. A remote attacker can spoof page content.


8) 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.


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) 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.


11) 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.


12) Input validation error (CVE-ID: CVE-2022-42837)

The vulnerability allows a remote attacker to execute arbitrary code on the system.

The vulnerability exists due to insufficient validation of URLs in iTunes Store. A remote attacker can trick the victim to open a specially crafted URL and execute arbitrary code on the system.


13) 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.


14) 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.


15) Out-of-bounds write (CVE-ID: CVE-2022-46694)

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a boundary error when processing untrusted video files in AppleAVD. A remote attacker can create a specially crafted video file, trick the victim into opening it using the affected software, trigger out-of-bounds write and execute arbitrary code on the target system.


16) Improper Privilege Management (CVE-ID: CVE-2022-42848)

The vulnerability allows a local application to escalate privileges on the device.

The vulnerability exists due to improper privilege management in AVEVideoEncoder. A local application can execute arbitrary code with kernel privileges.


17) Input validation error (CVE-ID: CVE-2022-42846)

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 Graphics Driver when processing video files. A remote attacker can trick the victim to open a specially crafted video file and perform a denial of service (DoS) attack.


18) 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.


19) Spoofing attack (CVE-ID: CVE-2022-46705)

The vulnerability allows a remote attacker to perform spoofing attack.

The vulnerability exists due to incorrect processing of URL in WebKit. A remote attacker can spoof the browser's address bar.


20) Buffer overflow (CVE-ID: CVE-2023-23496)

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.


21) Information disclosure (CVE-ID: CVE-2022-46718)
