Description
This security bulletin contains information about 21 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) Security features bypass (CVE-ID: CVE-2022-46872)
The vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due to unspecified error on Linux installations. A remote attacker who compromised content process can escaped the sandbox and read arbitrary files via clipboard-related IPC messages.
3) Security features bypass (CVE-ID: CVE-2022-46873)
The vulnerability allows a remote attacker to bypass certain security restrictions.
The vulnerability exists due to missing implementation of the unsafe-hashes CSP directive. A remote attacker can leverage such browser behavior to inject and execute potentially dangerous scripts.
4) Input validation error (CVE-ID: CVE-2022-46874)
The vulnerability allows a remote attacker to perform a spoofing attack.
The vulnerability exists due to insufficient validation of long filenames during drag and drop actions, which causes filename truncation to a potentially malicious extension. A remote attacker can trick the victim to download a file with a long filename, which can be automatically truncated by the browser into an executable file.
5) Insufficient UI Warning of Dangerous Operations (CVE-ID: CVE-2022-46875)
The vulnerability allows a remote attacker to perform spoofing attack.
The vulnerability exists due to executable file warning is not displayed when downloading .atloc and .ftploc files. A remote attacker can trick the victim into downloading and executing dangerous files.
Note, the vulnerability affects macOS installations only.
6) 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.
7) Buffer overflow (CVE-ID: CVE-2022-46878)
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 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.
8) Buffer overflow (CVE-ID: CVE-2022-46879)
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 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) Use-after-free (CVE-ID: CVE-2022-46880)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error in WebGL. 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.
10) Buffer overflow (CVE-ID: CVE-2022-46881)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error in WebGL. A remote attacker can trick the victim into opening 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.
11) Use-after-free (CVE-ID: CVE-2022-46882)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error in WebGL. 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.
12) 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.
13) 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.
14) 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.
15) 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.
16) 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.
17) 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.
18) 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.
19) 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.
20) 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.
21) 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.
