1) Out-of-bounds write (CVE-ID: CVE-2022-32792)

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a boundary error when processing untrusted input within the B3 JIT compiler in WebKit. A remote attacker can trick the victim into opening a specially crafted webpage, trigger an out-of-bounds write and execute arbitrary code on the target system.

2) Heap-based buffer overflow (CVE-ID: CVE-2022-2294)

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

The vulnerability exists due to a boundary error within WebRTC implementation. A remote attacker can trick the victim ti visit a specially crafted website, trigger a heap-based buffer overflow 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) Information disclosure (CVE-ID: CVE-2022-32784)

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

The vulnerability exists due to excessive data output by the Safari Extensions. A remote attacker can gain unauthorized access to sensitive information on the system.

4) Buffer overflow (CVE-ID: CVE-2022-32863)

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 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.

5) Information disclosure (CVE-ID: CVE-2022-32861)

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

The vulnerability exists due to a logic issue in WebKit. A remote attacker can track user's by their IP address.

6) Buffer overflow (CVE-ID: CVE-2022-32885)

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 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-2022-48503)

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 within the JavaScript code engine in WebKit. A remote attacker can trick the victim to visit a specially crafted website, trigger memory corruption and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
