Summary
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 triggered by processing a corrupted dump file and will result in hcidump crash.

Summary
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 one can craft a request where the response is large enough to overflow the preallocated buffer. This issue exists in service_attr_req gets called by process_request (in sdpd-request.c), which also allocates the response buffer.

Summary
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.

Summary
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 physically nearby attackers.

Summary
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.

Summary
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_req of sdpd-request.c. The server does not check whether the CSTATE data is the same in consecutive requests, and instead simply trusts that it is the same.

Summary
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.

var-202111-1603
Vulnerability from variot
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. BlueZ Contains a vulnerability regarding the lack of free memory after expiration.Service operation interruption (DoS) It may be in a state.
BlueZ has a resource management error vulnerability. The vulnerability stems from a vulnerability in the cstate alloc buf of the sdp in the affected version. ========================================================================== Ubuntu Security Notice USN-5155-1 November 23, 2021
bluez vulnerabilities
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 21.10
- Ubuntu 21.04
- Ubuntu 20.04 LTS
- Ubuntu 18.04 LTS
Summary:
Several security issues were fixed in BlueZ.
Software Description: - bluez: Bluetooth tools and daemons
Details:
It was discovered that BlueZ incorrectly handled the Discoverable status when a device is powered down. This could result in devices being powered up discoverable, contrary to expectations. This issue only affected Ubuntu 20.04 LTS, Ubuntu 21.04, and Ubuntu 21.10. (CVE-2021-3658)
It was discovered that BlueZ incorrectly handled certain memory operations. A remote attacker could possibly use this issue to cause BlueZ to consume resources, leading to a denial of service. (CVE-2021-41229)
It was discovered that the BlueZ gatt server incorrectly handled disconnects. (CVE-2021-43400)
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 21.10: bluez 5.60-0ubuntu2.1 libbluetooth3 5.60-0ubuntu2.1
Ubuntu 21.04: bluez 5.56-0ubuntu4.3 libbluetooth3 5.56-0ubuntu4.3
Ubuntu 20.04 LTS: bluez 5.53-0ubuntu3.4 libbluetooth3 5.53-0ubuntu3.4
Ubuntu 18.04 LTS: bluez 5.48-0ubuntu3.6 libbluetooth3 5.48-0ubuntu3.6
In general, a standard system update will make all the necessary changes. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256

"data": "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. BlueZ Contains a vulnerability regarding the lack of free memory after expiration.Service operation interruption (DoS) It may be in a state. \n\r\n\r\nBlueZ has a resource management error vulnerability. The vulnerability stems from a vulnerability in the cstate alloc buf of the sdp in the affected version. ==========================================================================\nUbuntu Security Notice USN-5155-1\nNovember 23, 2021\n\nbluez vulnerabilities\n==========================================================================\n\nA security issue affects these releases of Ubuntu and its derivatives:\n\n- Ubuntu 21.10\n- Ubuntu 21.04\n- Ubuntu 20.04 LTS\n- Ubuntu 18.04 LTS\n\nSummary:\n\nSeveral security issues were fixed in BlueZ. \n\nSoftware Description:\n- bluez: Bluetooth tools and daemons\n\nDetails:\n\nIt was discovered that BlueZ incorrectly handled the Discoverable status\nwhen a device is powered down. This could result in devices being powered\nup discoverable, contrary to expectations. This issue only affected Ubuntu\n20.04 LTS, Ubuntu 21.04, and Ubuntu 21.10. (CVE-2021-3658)\n\nIt was discovered that BlueZ incorrectly handled certain memory operations. \nA remote attacker could possibly use this issue to cause BlueZ to consume\nresources, leading to a denial of service. (CVE-2021-41229)\n\nIt was discovered that the BlueZ gatt server incorrectly handled\ndisconnects.
