Description
This security bulletin contains information about 5 secuirty vulnerabilities.
1) Integer overflow (CVE-ID: CVE-2021-22677)
The vulnerability allows a local attacker to execute arbitrary code on the target system.
The vulnerability exists due to integer overflow in the APIs of the host MCU. A local attacker can pass specially crafted data to the application, trigger integer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
2) Stack-based buffer overflow (CVE-ID: CVE-2021-22673)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when processing over-the-air firmware updates from the CDN server. A remote authenticated attacker can trigger stack-based buffer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
3) Integer overflow (CVE-ID: CVE-2021-22675)
The vulnerability allows a remote user to execute arbitrary code on the target system.
The vulnerability exists due to integer overflow while parsing malformed over-the-air firmware update files. A remote administrator can pass specially crafted data to the application, trigger integer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
4) Integer overflow (CVE-ID: CVE-2021-22679)
The vulnerability allows a remote user to execute arbitrary code on the target system.
The vulnerability exists due to integer overflow while processing HTTP headers. A remote attacker can pass specially crafted data to the application, trigger integer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
5) Integer overflow (CVE-ID: CVE-2021-22671)
The vulnerability allows a remote user to execute arbitrary code on the target system.
The vulnerability exists due to integer overflow while processing long domain names. A remote attacker can pass specially crafted data to the application, trigger integer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
