Description
This security bulletin contains information about 9 secuirty vulnerabilities.
1) Memory corruption (CVE-ID: CVE-2018-8384)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to boundary error when the Chakra scripting engine handles objects in memory in Microsoft Edge. A remote unauthenticated attacker can trick the victim into visiting a specially crafted website, trigger memory corruption and execute arbitrary code with elevated privileges.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
2) Memory corruption (CVE-ID: CVE-2018-8359)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to boundary error when the ChakraCore scripting engine handles objects in memory. A remote unauthenticated attacker can trick the victim into visiting a specially crafted website, trigger memory corruption and execute arbitrary code with elevated privileges.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
3) Memory corruption (CVE-ID: CVE-2018-8381)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to boundary error when the Chakra scripting engine handles objects in memory in Microsoft Edge. A remote unauthenticated attacker can trick the victim into visiting a specially crafted website, trigger memory corruption and execute arbitrary code with elevated privileges.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
4) Memory corruption (CVE-ID: CVE-2018-8380)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to boundary error when the Chakra scripting engine handles objects in memory in Microsoft Edge. A remote unauthenticated attacker can trick the victim into visiting a specially crafted website, trigger memory corruption and execute arbitrary code with elevated privileges.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
5) Memory corruption (CVE-ID: CVE-2018-8266)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to boundary error when the Chakra scripting engine handles objects in memory in Microsoft Edge. A remote unauthenticated attacker can trick the victim into visiting a specially crafted website, trigger memory corruption and execute arbitrary code with elevated privileges.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
6) Memory corruption (CVE-ID: CVE-2018-8355)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to boundary error when the scripting engine handles objects in memory in Microsoft browsers. A remote unauthenticated attacker can trick the victim into visiting a specially crafted website, trigger memory corruption and execute arbitrary code with elevated privileges.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
7) Memory corruption (CVE-ID: CVE-2018-8390)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to boundary error when the ChakraCore scripting engine handles objects in memory. A remote unauthenticated attacker can trick the victim into visiting a specially crafted website, trigger memory corruption and execute arbitrary code with elevated privileges.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
8) Memory corruption (CVE-ID: CVE-2018-8385)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to boundary error when the scripting engine handles objects in memory in Microsoft browsers. A remote unauthenticated attacker can trick the victim into visiting a specially crafted website, trigger memory corruption and execute arbitrary code with elevated privileges.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
9) Memory corruption (CVE-ID: CVE-2018-8372)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
