Description
This security bulletin contains information about 10 secuirty vulnerabilities.
1) Security features bypass (CVE-ID: CVE-2023-23597)
The vulnerability allows a remote attacker to read arbitrary files on the system.
The vulnerability exists due to a logic error in the process allocation. A compromised web child process can disable the web security opening restrictions and spawn a new child process within the file:// context, providing the ability to read arbitrary files on the system.
2) 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.
3) 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.
4) State Issues (CVE-ID: CVE-2023-23600)
The vulnerability allows a remote attacker to modify browser's behavior.
The vulnerability exists due to an error in the way per origin notifications are handled between normal and private browsing. As a result, an attacker can display notifications during different browsing sessions.
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) Security features bypass (CVE-ID: CVE-2023-23604)
The vulnerability allows a remote attacker to bypass implemented security restrictions.
The vulnerability exists due to the possibility to create a duplicate SystemPrincipal object when parsing a non-system html document via DOMParser::ParseFromSafeString. This could have lead to bypassing web security checks.
9) 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.
10) Buffer overflow (CVE-ID: CVE-2023-23606)
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.
