Bluez buffer overflow vulnerability (CNVD-2021-95605)

BlueZ is a Bluetooth protocol stack written in C. It is primarily used to provide support for the core Bluetooth layers and protocols. A security vulnerability exists in Bluetoothd in BlueZ version 5.48 and earlier, which stems from a program receiving data without any size checking, and which ca...

CVE-2019-8921

An issue was discovered in bluetoothd in BlueZ through version 5.48. The vulnerability lies in the handling of buffered data where it is possible to cause the server to return more bytes than the buffer actually holds, resulting in leaking arbitrary heap data...

CVE-2019-8922

A heap-based buffer overflow was discovered in bluetoothd in bluez through version 5.48. A missing check on whether there is enough space in the destination buffer can allow an attacker to exploit the vulnerability by crafting a request where the response is large enough to overflow the...
