Description
This security bulletin contains information about 11 secuirty vulnerabilities.
1) Use-after-free (CVE-ID: CVE-2023-4573)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error in IPC CanvasTranslator. A remote attacker can trick the victim to open a specially crafted website, trigger memory corruption and execute arbitrary code on the system.
Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.
2) Use-after-free (CVE-ID: CVE-2023-4574)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error in IPC ColorPickerShownCallback. A remote attacker can trick the victim to open a specially crafted website, trigger memory corruption and execute arbitrary code on the system.
Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.
3) Use-after-free (CVE-ID: CVE-2023-4575)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error in IPC FilePickerShownCallback. A remote attacker can trick the victim to open a specially crafted website, trigger memory corruption and execute arbitrary code on the system.
Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.
4) Buffer overflow (CVE-ID: CVE-2023-4577)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error in JIT UpdateRegExpStatics when UpdateRegExpStatics attempted to access initialStringHeap. 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.
5) Resource exhaustion (CVE-ID: CVE-2023-4578)
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 in JS::CheckRegExpSyntax. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.
6) Input validation error (CVE-ID: CVE-2023-4579)
The vulnerability allows a remote attacker to perform a spoofing attack.
The vulnerability exists due to insufficient validation of user-supplied input when handling persistent search terms. Search queries in the default search engine can appear to have been the currently navigated URL if the search query itself is a well formed URL. As a result, a remote attacker can perform a spoofing attack if it had been maliciously set as the default search engine.
7) Cleartext storage of sensitive information (CVE-ID: CVE-2023-4580)
The vulnerability allows a local user to gain access to sensitive information.
The vulnerability exists due to push notifications are saved to disk unencrypted. A local user can gain access to potentially sensitive information.
8) Insufficient UI Warning of Dangerous Operations (CVE-ID: CVE-2023-4581)
The vulnerability allows a remote attacker to bypass implemented security restrictions.
The vulnerability exists due to a missing warning when downloading Excel .xll add-in files. A remote attacker can trick the victim to visit a specially crafted website and force the browser to download potentially dangerous files without any warning.
9) Information disclosure (CVE-ID: CVE-2023-4583)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to private session data are not cleared in HttpBaseChannel when closing private window. A remote attacker can obtain information from the not cleared session.
10) Buffer overflow (CVE-ID: CVE-2023-4584)
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.
11) Buffer overflow (CVE-ID: CVE-2023-4585)
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.
