Name of the Vulnerable Software and Affected Versions
BlueZ (affected versions not specified)
Description
The issue is related to a heap-based buffer overflow in the Phone Book Access profile of BlueZ, which can be exploited by network-adjacent attackers to execute arbitrary code on affected installations. User interaction is required, as the target must connect to a malicious Bluetooth device. The flaw exists due to the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length heap-based buffer. This allows an attacker to execute code in the context of root.
Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
