BlueZ Phone Book Access Profile Heap-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of BlueZ. User interaction is required to exploit this vulnerability in that the target must connect to a malicious Bluetooth device.

The specific flaw exists within the handling of the Phone Book Access profile. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of root. Was ZDI-CAN-20936.

A vulnerability has been found in Linux Kernel and classified as problematic. This vulnerability affects the function jlinkinit of the file monitor/jlink.c of the component BlueZ. The manipulation leads to denial of service. It is recommended to apply a patch to fix this issue. The identifier of this vulnerability is VDB-211936.

A vulnerability classified as problematic has been found in Linux Kernel. Affected is the function read50controllercapcomplete of the file tools/mgmt-tester.c of the component BlueZ. The manipulation of the argument caplen leads to null pointer dereference. It is recommended to apply a patch to fix this issue. VDB-211086 is the identifier assigned to this vulnerability.

BlueZ is a Bluetooth protocol stack for Linux. In affected versions a vulnerability exists in sdpcstateallocbuf 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.

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.

A flaw was found in the Linux kernel. Improper access control in BlueZ may allow an authenticated user to potentially enable information disclosure via adjacent access. The highest threat from this vulnerability is to data confidentiality and integrity.

A bug in bluez prevents the disabling of Bluetooth discoverability. In certain situations, this flaw could potentially lead to the unauthorized pairing of Bluetooth devices.

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.

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

In BlueZ 5.42, a use-after-free was identified in "confopt" 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.

In BlueZ 5.42, a buffer overflow was observed in "commandsdump" 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.

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

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

In BlueZ 5.42, a buffer overflow was observed in "pincodereplydump" 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 "pincodereplycp cp" parameter.

In BlueZ 5.42, a buffer over-read was observed in "l2capdump" 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.

In BlueZ 5.42, a buffer over-read was identified in "l2cappacket" function in "monitor/packet.c" source file. This issue can be triggered by processing a corrupted dump file and will result in btmon crash.
