Description
This security bulletin contains information about 9 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) Input validation error (CVE-ID: CVE-2021-34145)
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 LMP_max_slot with an invalid Baseband packet type and LT_ADDRESS. A remote attacker in radio range can send a specially crafted LMP packet and perform a denial of service (DoS) attack.
6) Input validation error (CVE-ID: CVE-2021-34148)
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 LMP_max_slot with a higher ACL Length after completion of the LMP setup procedure. A remote attacker in radio range can send a specially crafted LMP packet and perform a denial of service (DoS) attack.
7) Input validation error (CVE-ID: CVE-2021-34147)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to the Bluetooth Classic implementations does not properly handle the reception of a malformed LMP timing accuracy response followed by multiple re-connections to the target link slave. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.
8) Input validation error (CVE-ID: N/A)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to the Bluetooth Classic implementations does not properly handle the reception of a malformed LMP timing accuracy response followed by multiple re-connections to the target link slave. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.
9) Input validation error (CVE-ID: N/A)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to the Bluetooth Classic implementations does not properly handle the reception of a malformed LMP timing accuracy response followed by multiple re-connections to the target link slave. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.
