Bluez Security Vulnerabilities

CVE-2016-7837

Buffer overflow in BlueZ 5.41 and earlier allows an attacker to execute arbitrary code via the parse_line function used in some userland utilities.

CVE-2016-9797

In BlueZ 5.42, a buffer over-read was observed in "l2cap_dump" function in "tools/parser/l2cap.c" source file. This issue can be triggered by processing a corrupted dump file and will result in hcidump crash.

CVE-2016-9798

In BlueZ 5.42, a use-after-free was identified in "conf_opt" function in "tools/parser/l2cap.c" source file. This issue can be triggered by processing a corrupted dump file and will result in hcidump crash.

CVE-2016-9799

In BlueZ 5.42, a buffer overflow was observed in "pklg_read_hci" function in "btsnoop.c" source file. This issue can be triggered by processing a corrupted dump file and will result in btmon crash.

CVE-2016-9800

In BlueZ 5.42, a buffer overflow was observed in "pin_code_reply_dump" function in "tools/parser/hci.c" source file. The issue exists because "pin" array is overflowed by supplied parameter due to lack of boundary checks on size of the buffer from frame "pin_code_reply_cp *cp" parameter.

CVE-2016-9801

In BlueZ 5.42, a buffer overflow was observed in "set_ext_ctrl" function in "tools/parser/l2cap.c" source file when processing corrupted dump file.

CVE-2016-9802

In BlueZ 5.42, a buffer over-read was identified in "l2cap_packet" function in "monitor/packet.c" source file. This issue can be triggered by processing a corrupted dump file and will result in btmon crash.

CVE-2016-9803

In BlueZ 5.42, an out-of-bounds read was observed in "le_meta_ev_dump" function in "tools/parser/hci.c" source file. This issue exists because 'subevent' (which is used to read correct element from 'ev_le_meta_str' array) is overflowed.

CVE-2016-9804

In BlueZ 5.42, a buffer overflow was observed in "commands_dump" function in "tools/parser/csr.c" source file. The issue exists because "commands" array is overflowed by supplied parameter due to lack of boundary checks on size of the buffer from frame "frm->ptr" parameter. This issue can be tri...

CVE-2016-9917

In BlueZ 5.42, a buffer overflow was observed in "read_n" function in "tools/hcidump.c" source file. This issue can be triggered by processing a corrupted dump file and will result in hcidump crash.

CVE-2017-1000250

All versions of the SDP server in BlueZ 5.46 and earlier are vulnerable to an information disclosure vulnerability which allows remote attackers to obtain sensitive information from the bluetoothd process memory. This vulnerability lies in the processing of SDP search attribute requests.

CVE-2018-10910

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.

CVE-2019-8921

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 arbitrar...

CVE-2019-8922

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. Th...

CVE-2020-0556

Improper access control in subsystem for BlueZ before version 5.54 may allow an unauthenticated user to potentially enable escalation of privilege and denial of service via adjacent access

CVE-2020-24490

Improper buffer restrictions in BlueZ may allow an unauthenticated user to potentially enable denial of service via adjacent access. This affects all Linux kernel versions that support BlueZ.

CVE-2020-27153

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-2021-0129

Improper access control in BlueZ may allow an authenticated user to potentially enable information disclosure via adjacent access.

CVE-2021-3588

The cli_feat_read_cb() function in src/gatt-database.c does not perform bounds checks on the 'offset' variable before using it as an index into an array for reading.

CVE-2021-3658

bluetoothd from bluez incorrectly saves adapters' Discoverable status when a device is powered down, and restores it when powered up. If a device is powered down while discoverable, it will be discoverable when powered on again. This could lead to inadvertent exposure of the bluetooth stack to phys...

CVE-2021-41229

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 objec...

CVE-2021-43400

An issue was discovered in gatt-database.c in BlueZ 5.61. A use-after-free can occur when a client disconnects during D-Bus processing of a WriteValue call.

CVE-2022-0204

A heap overflow vulnerability was found in bluez in versions prior to 5.63. An attacker with local network access could pass specially crafted files causing an application to halt or crash, leading to a denial of service.

CVE-2022-3563

A vulnerability classified as problematic has been found in Linux Kernel. Affected is the function read_50_controller_cap_complete of the file tools/mgmt-tester.c of the component BlueZ.
