In BlueZ before 5.55, a double free was found in the gatttool disconnect_cb() routine from shared/att.c. A remote attacker could potentially cause a denial of service or code execution, during service discovery, due to a redundant disconnect MGMT event.

CVE-2020-26558 [MEDIUM] CVE-2020-26558: bluez - Bluetooth LE and BR/EDR secure pairing in Bluetooth Core Specification 2.1 throu... Bluetooth LE and BR/EDR secure pairing in Bluetooth Core Specification 2.1 through 5.2 may permit a nearby man-in-the-middle attacker to identify the Passkey used during pairing (in the Passkey authentication procedure) by reflection of the public key and the authentication evidence of the initiating device, potentially permitting this attacker to complete authentic

CVE-2019-8922 [HIGH] CVE-2019-8922: bluez - A heap-based buffer overflow was discovered in bluetoothd in BlueZ through 5.48.... A heap-based buffer overflow was discovered in bluetoothd in BlueZ through 5.48. There isn't any check on whether there is enough space in the destination buffer. The function simply appends all data passed to it. The values of all attributes that are requested are appended to the output buffer. There are no size checks whatsoever, resulting in a simple heap overflow if

CVE-2019-8921 [MEDIUM] CVE-2019-8921: bluez - An issue was discovered in bluetoothd in BlueZ through 5.48. The vulnerability l... An issue was discovered in bluetoothd in BlueZ through 5.48. The vulnerability lies in the handling of a SVC_ATTR_REQ by the SDP implementation. By crafting a malicious CSTATE, it is possible to trick the server into returning more bytes than the buffer actually holds, resulting in leaking arbitrary heap data. The root cause can be found in the function service_attr_r

A bug in Bluez may allow for the Bluetooth Discoverable state being set to on when no Bluetooth agent is registered with the system. This situation could lead to the unauthorized pairing of certain Bluetooth devices without any form of authentication. Versions before bluez 5.51 are vulnerable.
