Description
This security bulletin contains information about 14 secuirty vulnerabilities.
1) Origin validation error (CVE-ID: CVE-2023-4045)
The vulnerability allows a remote attacker to bypass implemented security restrictions.
The vulnerability exists due to improper tracking of cross-origin tainting in Offscreen Canvas. A remote attacker can violation the same-origin policy and access image data from another website.
2) State Issues (CVE-ID: CVE-2023-4046)
The vulnerability allows a remote attacker to compromise the affected system.
The vulnerability exists due to usage of incorrect values during WASM compilation, resulting in a state value to be used for a global variable in WASM JIT analysis in the content process. A remote attacker can trick the victim into opening a malicious web page and execute arbitrary code on the system.
3) Insufficient UI Warning of Dangerous Operations (CVE-ID: CVE-2023-4047)
The vulnerability allows a remote attacker to perform clickjacking attacks.
The vulnerability exists due to an error in popup notifications delay calculation. A remote attacker can trick the victim into granting permissions.
4) Resource exhaustion (CVE-ID: CVE-2023-4048)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to application does not properly control consumption of internal resources when parsing HTML with DOMParser. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.
5) Use-after-free (CVE-ID: CVE-2023-4049)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error when releasing platform objects. A remote attacker can trick the victim to open a specially crafted web page, trigger a race condition and execute arbitrary code.
Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.
6) Stack-based buffer overflow (CVE-ID: CVE-2023-4050)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error in StorageManager when processing an untrusted input stream. A remote attacker can trick the victim to open a specially crafted website, trigger a stack-based buffer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
7) Insufficient UI Warning of Dangerous Operations (CVE-ID: CVE-2023-4051)
The vulnerability allows a remote attacker to perform spoofing attack.
The vulnerability exists due to an error when displaying the full screen notification by using the file open dialog. A remote attacker can trick the victim into clocking on the file open dialog and perform spoofing attack.
8) Insecure Inherited Permissions (CVE-ID: CVE-2023-4052)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to Firefox uninstaller follows symbolic links when removing files from directory created by the application updater that is writable by non-privileged users. A local user can create symbolic links to critical files on the system and delete them when uninstalling Firefox.
Note, the vulnerability affects Windows installations only.
9) Insufficient UI Warning of Dangerous Operations (CVE-ID: CVE-2023-4053)
The vulnerability allows a remote attacker to perform spoofing attack.
The vulnerability exists due an error when handling full screen notifications. A malicious website can obscure the full screen notification by using a
URL with a scheme handled by an external program, such as a mailto URL, and perform spoofing attack.
10) Insufficient UI Warning of Dangerous Operations (CVE-ID: CVE-2023-4054)
The vulnerability allows a remote attacker to compromise the affected system.
The vulnerability exists due to a missing warning when opening appref-ms files. A remote attacker can trick the victim to open a malicious appref-ms file and compromise the affected system.
Note, the vulnerability affects Windows installations only.
11) State Issues (CVE-ID: CVE-2023-4055)
The vulnerability allows a remote attacker to tamper with HTTP requests.
The vulnerability exists due to a cookie jar overflow when the number of cookies per domain was exceeded in document.cookie. A remote attacker can tamper with HTTP request and force the browser to send requests with some cookies missing.
12) Buffer overflow (CVE-ID: CVE-2023-4056)
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 into opening a specially crafted web page, trigger memory corruption and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
13) Buffer overflow (CVE-ID: CVE-2023-4057)
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 into opening a specially crafted web page, trigger memory corruption and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
14) Buffer overflow (CVE-ID: CVE-2023-4058)
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 into opening a specially crafted web page, trigger memory corruption and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
