Description
This security bulletin contains information about 9 secuirty vulnerabilities.
1) Information disclosure (CVE-ID: CVE-2022-46698)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to excessive data output in WebKit. A remote attacker can gain unauthorized access to sensitive information on the system.
2) Buffer overflow (CVE-ID: CVE-2022-42863)
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.
3) Buffer overflow (CVE-ID: CVE-2022-46699)
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) 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.
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) 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.
7) 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.
8) Buffer overflow (CVE-ID: CVE-2022-42867)
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.
9) 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.
