Description
This security bulletin contains information about 12 secuirty vulnerabilities.
1) Buffer overflow (CVE-ID: CVE-2023-5731)
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.
2) Spoofing attack (CVE-ID: CVE-2023-5729)
The vulnerability allows a remote attacker to perform spoofing attack.
The vulnerability exists due to incorrect processing of user-supplied data. A malicious web site can enter fullscreen mode while simultaneously triggering a WebAuthn prompt. This could have obscured the fullscreen notification and could have been leveraged in a spoofing attack.
3) Input validation error (CVE-ID: CVE-2023-5723)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied input when handling invalid cookie characters. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.
4) Information disclosure (CVE-ID: CVE-2023-5722)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to cross-origin size and header leakage. A remote attacker can learn the size of an opaque response using iterative requests.
5) Buffer overflow (CVE-ID: CVE-2023-5730)
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.
6) Buffer overflow (CVE-ID: CVE-2023-5728)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to improper object tracking during garbage collection. 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) Security features bypass (CVE-ID: CVE-2023-5727)
The vulnerability allows a remote attacker to bypass implemented security restrictions.
The vulnerability exists due to a missing executable file warning when downloading .msix, .msixbundle, .appx, and .appxbundle files. A remote attacker can trick the victim into executing the files and compromise the affected system.
The vulnerability affects Windows installations only.
8) Spoofing attack (CVE-ID: CVE-2023-5726)
The vulnerability allows a remote attacker to perform spoofing attack.
The vulnerability exists due to incorrect processing of user-supplied data when handling fullscreen notifications by file opening dialog. A remote attacker can perform spoofing attack.
Note, the vulnerability affects macOS installation only.
9) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2023-5725)
The vulnerability allows a malicious extension to bypass implemented security restrictions.
The vulnerability exists due to improperly imposed security restrictions in WebExtension, which can open arbitrary URLs. A malicious extension can collect sensitive user data.
10) Resource management error (CVE-ID: CVE-2023-5724)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to improper management of internal resources in WebGL. A remote attacker can trick the victim to open a specially crafted website and perform a denial of service (DoS) attack.
11) Spoofing attack (CVE-ID: CVE-2023-5732)
The vulnerability allows a remote attacker to perform spoofing attack.
The vulnerability exists due to incorrect processing of user-supplied data when handling bidirectional characters. A remote attacker can spoof the browser address bar.
12) Spoofing attack (CVE-ID: CVE-2023-5721)
The vulnerability allows a remote attacker to perform spoofing attack.
The vulnerability exists due to incorrect processing of queued up rendering. A remote attacker can perform spoofing attack by activating or dismissing certain browser prompts and dialogs.
