Description
This security bulletin contains information about 13 secuirty vulnerabilities.
1) Buffer overflow (CVE-ID: CVE-2020-0768)
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 content within the the ChakraCore scripting engine in Microsoft browsers. A remote attacker can create a specially crafted web page, 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) Buffer overflow (CVE-ID: CVE-2020-0823)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error within the ChakraCore scripting engine. A remote attacker can create a specially crafted webpage, trick the victim into opening 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) Out-of-bounds read (CVE-ID: CVE-2020-0813)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition when processing untrusted data in Chakra scripting engine. A remote attacker who knows the memory address of where the object was created can trigger out-of-bounds read error and read contents of memory on the system.

The vulnerability exists due to a boundary error within the Chakra scripting engine in Microsoft Edge (HTML-based). A remote attacker can create a specially crafted webpage, trick the victim into opening 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) Buffer overflow (CVE-ID: CVE-2020-0831)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error within the ChakraCore scripting engine. A remote attacker can create a specially crafted webpage, trick the victim into opening 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) Buffer overflow (CVE-ID: CVE-2020-0830)
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 content within the the ChakraCore scripting engine in Microsoft browsers. A remote attacker can create a specially crafted web page, 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.
8) Buffer overflow (CVE-ID: CVE-2020-0829)
