CVE-ID: CVE-2018-8643
CWE-ID:
CWE-119 - Improper Restriction of Operations within the Bounds of a Memory Buffer
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when the scripting engine handles objects in memory in Internet Explorer. A remote attacker can create a specially 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.

CVE-ID: CVE-2018-8619
CWE-ID:
CWE-119 - Improper Restriction of Operations within the Bounds of a Memory Buffer
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when the Internet Explorer VBScript execution policy does not properly restrict VBScript under specific conditions. 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.
