Description

This security bulletin contains information about 8 secuirty vulnerabilities.


1) Heap-based buffer overflow (CVE-ID: CVE-2023-50230)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error within the handling of the Phone Book Access profile. A remote attacker on the local network can pass specially crafted data to the application, trigger a heap-based buffer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.


2) Heap-based buffer overflow (CVE-ID: CVE-2023-50229)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error within the handling of the Phone Book Access profile. A remote attacker on the local network can pass specially crafted data to the application, trigger a heap-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) Out-of-bounds read (CVE-ID: CVE-2023-51594)

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to a boundary condition when handling OBEX protocol parameter. A remote attacker can trick the victim into connecting to a malicious device, trigger an out-of-bounds read and gain access to sensitive information.


4) Heap-based buffer overflow (CVE-ID: CVE-2023-51596)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error when handling the Phone Book Access profile. A remote attacker can trick the victim into connection to a malicious Bluetooth device, trigger a heap-based buffer overflow and execute arbitrary code on the system.


5) Stack-based buffer overflow (CVE-ID: CVE-2023-44431)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error when handling AVRCP protocol. A remote attacker can trick the victim into connection to a malicious Bluetooth device, trigger a stack-based buffer overflow and execute arbitrary code on the system.

6) Out-of-bounds read (CVE-ID: CVE-2023-51580)

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to a boundary condition when handling AVRCP protocol within the avrcp_parse_attribute_list() function. A remote attacker can trick the victim into connecting to a malicious device, trigger an out-of-bounds read and gain access to sensitive information.

7) Out-of-bounds read (CVE-ID: CVE-2023-51592)

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to a boundary condition when handling AVRCP protocol within the parse_media_folder() function. A remote attacker can trick the victim into connecting to a malicious device, trigger an out-of-bounds read and gain access to sensitive information.


8) Out-of-bounds read (CVE-ID: CVE-2023-51589)

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to a boundary condition when handling AVRCP protocol within the parse_media_element() function. A remote attacker can trick the victim into connecting to a malicious device, trigger an out-of-bounds read and gain access to sensitive information.
