BlueZ Audio Profile AVRCP Stack-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code via Bluetooth on affected installations of BlueZ. User interaction is required to exploit this vulnerability in that the target must connect to a malicious device. The specific flaw exists within the handling of the AVRCP protocol. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of root. Was ZDI-CAN-19909.

The remote Redhat Enterprise Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2024:9413 advisory.

    The bluez packages contain the following utilities for use in Bluetooth applications: hcitool, hciattach,     hciconfig, bluetoothd, l2ping, start scripts (Red Hat), and pcmcia configuration files.

    Security Fix(es):

    * bluez: unauthorized HID device connections allows keystroke injection and arbitrary commands execution     (CVE-2023-45866)

    * BlueZ: Audio Profile AVRCP Improper Validation of Array Index Remote Code Execution Vulnerability     (CVE-2023-27349)
