Description
This security bulletin contains information about 15 secuirty vulnerabilities.
1) Spoofing attack (CVE-ID: CVE-2018-8425)
The disclosed vulnerability allows a remote attacker to perform spoofing attacks.
The vulnerability exists due to insufficient sanitization of user-supplied data. A remote attacker can trick the victim to follow a specially crafted link and spoof the content of the website.
2) Information disclosure (CVE-ID: CVE-2018-8366)
The vulnerability allows a remote attacker to obtain potentially sensitive information.
The vulnerability exists when the Microsoft Edge Fetch API incorrectly handles a filtered response type. A remote attacker can create a specially crafted web page, bypass the cross-origin policy and view URL of a cross-origin request.
3) Security restrictions bypass (CVE-ID: CVE-2018-8463)
The disclosed vulnerability allows a remote attacker to bypass certain security restrictions.
The vulnerability exists due to insufficient sanitization of user-supplied data. A remote attacker can trick the victim to visit a specially crafted web page, bypass AppContainer sandbox and execute arbitrary JavaScript code with elevated privileges.
4) Buffer overflow (CVE-ID: CVE-2018-8464)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to boundary error within the Microsoft PDF reader when processing PDF files. A remote unauthenticated attacker can trick the victim into opening a specially crafted PDF file, 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) Security restrictions bypass (CVE-ID: CVE-2018-8469)
The disclosed vulnerability allows a remote attacker to bypass certain security restrictions.
The vulnerability exists due to insufficient sanitization of user-supplied data. A remote attacker can trick the victim to visit a specially crafted web page, bypass AppContainer sandbox and execute arbitrary JavaScript code with elevated privileges.
6) Buffer over-read (CVE-ID: CVE-2018-8315)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary error while handling object types when parsing HTML content. A remote attacker can create a specially crafted web page, trick the victim into opening it, trigger out-of-bounds read and gain access to contents of memory.
7) Buffer over-read (CVE-ID: CVE-2018-8452)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary error when parsing HTML content. A remote attacker can create a specially crafted web page, trick the victim into opening it, trigger out-of-bounds read and gain access to contents of memory.
8) Memory corruption (CVE-ID: CVE-2018-8367)
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 code within the ChakraCore scripting engine. A remote attacker can create a specially crafted website, trick the victim into visiting 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.
9) Memory corruption (CVE-ID: CVE-2018-8456)
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 code within the ChakraCore scripting engine. A remote attacker can create a specially crafted website, trick the victim into visiting 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.
10) Memory corruption (CVE-ID: CVE-2018-8457)
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 code within the scripting engine. A remote attacker can create a specially crafted website, trick the victim into visiting 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) Memory corruption (CVE-ID: CVE-2018-8459)
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 code within the ChakraCore scripting engine. A remote attacker can create a specially crafted website, trick the victim into visiting it, trigger memory corruption and execute arbitrary code on the target system.
