Description

This security bulletin contains information about 4 secuirty vulnerabilities.


1) Heap-based buffer overflow (CVE-ID: CVE-2021-31610)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to the Bluetooth Classic implementation on several chipsets does not properly handle the reception of continuous unsolicited LMP responses. A remote attacker in radio range can pass specially crafted data to the application, trigger heap-based buffer overflow and cause a denial of service condition on the target system.


2) Heap-based buffer overflow (CVE-ID: CVE-2021-34149)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to the Bluetooth Classic implementation on several chipsets does not properly handle the reception of continuous unsolicited LMP responses. A remote attacker in radio range can pass specially crafted data to the application, trigger heap-based buffer overflow and cause a denial of service condition on the target system.


3) Heap-based buffer overflow (CVE-ID: CVE-2021-34146)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to the Bluetooth Classic implementation on several chipsets does not properly handle the reception of continuous unsolicited LMP responses. A remote attacker in radio range can pass specially crafted data to the application, trigger heap-based buffer overflow and cause a denial of service condition on the target system.


4) Heap-based buffer overflow (CVE-ID: CVE-2021-34143)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to the Bluetooth Classic implementation on several chipsets does not properly handle the reception of continuous unsolicited LMP responses. A remote attacker in radio range can pass specially crafted data to the application, trigger heap-based buffer overflow and cause a denial of service condition on the target system.
