Description
This security bulletin contains information about 10 secuirty vulnerabilities.
1) Use-after-free (CVE-ID: CVE-2023-28198)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error in WebKit. A remote attacker can trick the victim to open a specially crafted website, trigger a use-after-free error and execute arbitrary code on the system.
Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.
2) Security features bypass (CVE-ID: CVE-2023-32370)
The vulnerability allows a remote attacker to bypass implemented security restrictions.
The vulnerability exists due to an error in WebKit, as Content Security Policy may fail to block domains with wildcards. A remote attacker can bypass implemented CSP restrictions.
3) Buffer overflow (CVE-ID: CVE-2023-37450)
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 visiting 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.
4) Buffer overflow (CVE-ID: CVE-2023-38594)
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.
5) Buffer overflow (CVE-ID: CVE-2023-38595)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error 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.
6) Buffer overflow (CVE-ID: CVE-2023-38597)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error in WebKit Process Model. 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) Information disclosure (CVE-ID: CVE-2023-38599)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a logic issue in WebKit, related to user's privacy. A remote attacker can sensitive user information.
8) Buffer overflow (CVE-ID: CVE-2023-38600)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error 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.
9) Buffer overflow (CVE-ID: CVE-2023-38611)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error 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.
10) Code Injection (CVE-ID: CVE-2023-40397)
The vulnerability allows a remote attacker to execute arbitrary JavaScript code on the target system.
The vulnerability exists due to improper input validation. A remote attacker can trick the victim to visit a specially crafted webpage and execute arbitrary JavaScript code on the system.
Successful exploitation of the vulnerability may allow an attacker to compromise the affected system.
