Description
This security bulletin contains information about 11 secuirty vulnerabilities.
1) Buffer overflow (CVE-ID: CVE-2018-8461)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to boundary error when processing HTML code. A remote unauthenticated 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) Memory corruption (CVE-ID: CVE-2018-8354)
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 code within the ChakraCore scripting engine. 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-2018-8459)
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 code within the ChakraCore scripting engine. 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-2018-8456)
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 code within the ChakraCore scripting engine. 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-2018-8391)
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 code within the ChakraCore scripting engine. 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-2018-8367)
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 code within the ChakraCore scripting engine. 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) Buffer over-read (CVE-ID: CVE-2018-8452)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary error when parsing HTML content. A remote attacker can create a specially crafted web page, trick the victim into opening it, trigger out-of-bounds read and gain access to contents of memory.
8) Buffer over-read (CVE-ID: CVE-2018-8315)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary error while handling object types when parsing HTML content. A remote attacker can create a specially crafted web page, trick the victim into opening it, trigger out-of-bounds read and gain access to contents of memory.
9) Memory corruption (CVE-ID: CVE-2018-8467)
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 code within the ChakraCore scripting engine. 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.
10) Memory corruption (CVE-ID: CVE-2018-8466)
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 code within the ChakraCore scripting engine. 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.
11) Memory corruption (CVE-ID: CVE-2018-8465)
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 code within the ChakraCore scripting engine. 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.
