Description

This security bulletin contains information about 7 secuirty vulnerabilities.

1) Memory corruption (CVE-ID: CVE-2018-8500)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error when the ChakraCore scripting engine handles objects in memory. 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.

2) Memory corruption (CVE-ID: CVE-2018-8473)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error when Microsoft Edge improperly accesses objects in memory. 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.

3) Memory corruption (CVE-ID: CVE-2018-8503)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error when the Chakra scripting engine handles objects in memory in Microsoft Edge. 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.

4) Memory corruption (CVE-ID: CVE-2018-8505)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error when the Chakra scripting engine handles objects in memory in Microsoft Edge. 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.

5) Memory corruption (CVE-ID: CVE-2018-8510)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error when the Chakra scripting engine handles objects in memory in Microsoft Edge. 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.

6) Memory corruption (CVE-ID: CVE-2018-8511)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error when the Chakra scripting engine handles objects in memory in Microsoft Edge. 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.

7) Memory corruption (CVE-ID: CVE-2018-8513)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error when the Chakra scripting engine handles objects in memory in Microsoft Edge. 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.
