Description
This security bulletin contains information about 7 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-2022-46877)
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.
6) 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.
7) 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.
