Description
This security bulletin contains information about 13 secuirty vulnerabilities.
1) Use-after-free (CVE-ID: CVE-2023-3600)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error during the worker lifecycle when processing HTML content. A remote attacker can trick the victim to visit 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.
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) 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.
4) 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.
5) 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.
6) 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.
7) 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.
8) 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.
9) 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.
10) Heap-based buffer overflow (CVE-ID: CVE-2023-5217)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a boundary error when processing untrusted HTML content in vp8 encoding in libvpx. A remote attacker can create a specially crafted web page, trick the victim into opening it, trigger a heap-based buffer overflow and execute arbitrary code on the target system.
Note, the vulnerability is being actively exploited in the wild.
11) Buffer overflow (CVE-ID: CVE-2023-32213)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error within FileReader::DoReadData() when reading a file. A remote attacker can trigger memory corruption and execute arbitrary code on the target system.
12) Spoofing attack (CVE-ID: CVE-2023-32212)
The vulnerability allows a remote attacker to perform spoofing attack.
The vulnerability exists due to incorrect processing of user-supplied data. A remote attacker can spoof the address bar using the datalist element.
13) Type Confusion (CVE-ID: CVE-2023-32211)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a type confusion error when processing HTML content. A remote attacker can trick the victim to open a specially crafted website, trigger a type confusion error and crash the browser.
