Description
This security bulletin contains information about 8 secuirty vulnerabilities.
1) Buffer overflow (CVE-ID: CVE-2022-46871)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error in libusrsctp. A remote attacker can trigger memory corruption and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
2) Insufficient UI Warning of Dangerous Operations (CVE-ID: CVE-2022-46877)
The vulnerability allows a remote attacker to perform spoofing attack.
The vulnerability exists due to the way fullscreen notifications are displayed by the browser. A remote attacker can confuse browser to delay or suppress fullscreen notifications and perform spoofing attack.
3) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2023-23598)
The vulnerability allows a remote attacker to read arbitrary files on the system.
The vulnerability exists due to improperly imposed security restrictions with the Firefox GTK wrapper. A remote attacker can trick the victim to perform certain actions on the web page, such as drag objects and read arbitrary files on the system via a call to DataTransfer.setData.
4) OS Command Injection (CVE-ID: CVE-2023-23599)
The vulnerability allows a remote attacker to execute arbitrary shell commands on the target system.
The vulnerability exists due to improper input validation when copying a network request from the developer tools panel as a curl command in devtools on Windows. A remote attacker can trick the victim to copy and paste data from the network request into a console and execute arbitrary commands.
5) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2023-23601)
The vulnerability allows a remote attacker to perform spoofing attacks.
The vulnerability exists due to the way browser treats dragging of URL from the cross-origin iframe into the same tab. A remote attacker can perform spoofing attack.
6) Security features bypass (CVE-ID: CVE-2023-23602)
The vulnerability allows a remote attacker to bypass implemented security restrictions.
The vulnerability exists due to incorrect processing of CSP. A mishandled security check when creating a WebSocket in a WebWorker caused the Content Security Policy connect-src header to be ignored. This could lead to connections to restricted origins from inside WebWorkers.
7) Incorrect Regular Expression (CVE-ID: CVE-2023-23603)
The vulnerability allows a remote attacker to bypass implemented security restrictions.
The vulnerability exists due to usage of an incorrect regular expression when filtering out forbidden properties and values from style directives in calls to console.log. A remote attacker can exfiltrate data from the victim's browser.
8) Buffer overflow (CVE-ID: CVE-2023-23605)
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. 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.
