Description
This security bulletin contains information about 10 secuirty vulnerabilities.
1) Memory corruption (CVE-ID: CVE-2017-11871)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to improper handling of objects in memory in Microsoft Edge by the scripting engine. A remote attacker can create a specially crafted Web site, trick the victim into visiting it, trigger memory corruption and execute arbitrary code on the target system with privileges of the current user.
Successful exploitation of this vulnerability may result in remote code execution.
2) Memory corruption (CVE-ID: CVE-2017-11840)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to improper handling of objects in memory in Microsoft Edge by the scripting engine. A remote attacker can create a specially crafted Web site, trick the victim into visiting it, trigger memory corruption and execute arbitrary code on the target system with privileges of the current user.
Successful exploitation of this vulnerability may result in remote code execution.
3) Memory corruption (CVE-ID: CVE-2017-11836)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to improper handling of objects in memory in Microsoft Edge by the scripting engine. A remote attacker can create a specially crafted Web site, trick the victim into visiting it, trigger memory corruption and execute arbitrary code on the target system with privileges of the current user.
Successful exploitation of this vulnerability may result in remote code execution.
4) Memory corruption (CVE-ID: CVE-2017-11873)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to improper handling of objects in memory in Microsoft Edge by the scripting engine. A remote attacker can create a specially crafted Web site, trick the victim into visiting it, trigger memory corruption and execute arbitrary code on the target system with privileges of the current user.
Successful exploitation of this vulnerability may result in remote code execution.
5) Memory corruption (CVE-ID: CVE-2017-11870)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to improper handling of objects in memory in Microsoft Edge by the scripting engine. A remote attacker can create a specially crafted Web site, trick the victim into visiting it, trigger memory corruption and execute arbitrary code on the target system with privileges of the current user.
Successful exploitation of this vulnerability may result in remote code execution.
6) Memory corruption (CVE-ID: CVE-2017-11862)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to improper handling of objects in memory in Microsoft Edge by the scripting engine. A remote attacker can create a specially crafted Web site, trick the victim into visiting it, trigger memory corruption and execute arbitrary code on the target system with privileges of the current user.
Successful exploitation of this vulnerability may result in remote code execution.
7) Memory corruption (CVE-ID: CVE-2017-11861)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to improper handling of objects in memory in Microsoft Edge by the scripting engine. A remote attacker can create a specially crafted Web site, trick the victim into visiting it, trigger memory corruption and execute arbitrary code on the target system with privileges of the current user.
Successful exploitation of this vulnerability may result in remote code execution.
8) Memory corruption (CVE-ID: CVE-2017-11841)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to improper handling of objects in memory in Microsoft Edge by the scripting engine. A remote attacker can create a specially crafted Web site, trick the victim into visiting it, trigger memory corruption and execute arbitrary code on the target system with privileges of the current user.
Successful exploitation of this vulnerability may result in remote code execution.
9) Memory corruption (CVE-ID: CVE-2017-11837)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to improper handling of objects in memory in Microsoft Edge by the scripting engine. A remote attacker can create a specially crafted Web site, trick the victim into visiting it, trigger memory corruption and execute arbitrary code on the target system with privileges of the current user.
Successful exploitation of this vulnerability may result in remote code execution.
10) Security restrictions bypass (CVE-ID: CVE-2017-11874)
The vulnerability allows a remote authenticated attacker to bypass security restrictions on the target system.
The vulnerability exists due to how memory is accessed in code compiled by the Edge Just-In-Time (JIT) compiler. A remote attacker can browse to a malicious website, bypass Control Flow Guard (CFG) and perform further attacks.
