Description
This security bulletin contains information about 5 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.
5) Buffer overflow (CVE-ID: CVE-2021-34150)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to the Bluetooth Classic implementation does not properly handle the reception of oversized DM1 LMP packets. A remote attacker in radio range can send a specially crafted LMP packet, trigger memory corruption and cause a denial of service condition on the target system.
