BlueZ Phone Book Access Profile Heap-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of BlueZ. User interaction is required to exploit this vulnerability in that the target must connect to a malicious Bluetooth device. The specific flaw exists within the handling of the Phone Book Access profile. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of root. Was ZDI-CAN-20936.

The remote Oracle Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2024-9413 advisory.

  - BlueZ is a Bluetooth protocol stack for Linux. In affected versions a vulnerability exists in     sdp_cstate_alloc_buf which allocates memory which will always be hung in the singly linked list of cstates     and will not be freed. This will cause a memory leak over time. The data can be a very large object, which     can be caused by an attacker continuously sending sdp packets and this may cause the service of the target     device to crash. (CVE-2021-41229)
