The remote Debian 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-2827 advisory.

    Several vulnerabilities were discovered in BlueZ, the Linux Bluetooth protocol stack. An attacker could     cause a denial-of-service (DoS) or leak information. CVE-2019-8921 SDP infoleak; the vulnerability lies in     the handling of a SVC_ATTR_REQ by the SDP implementation of BlueZ. 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. CVE-2019-8922 SDP Heap Overflow; this vulnerability lies in the SDP protocol     handling of attribute requests as well. By requesting a huge number of attributes at the same time, an     attacker can overflow the static buffer provided to hold the response. CVE-2021-41229 sdp_cstate_alloc_buf     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.
    For Debian 9 stretch, these problems have been fixed in version 5.43-2+deb9u5. We recommend that you     upgrade your bluez packages. For the detailed security status of bluez please refer to its security     tracker page at: https://security-tracker.debian.org/tracker/bluez Further information about Debian LTS     security advisories, how to apply these updates to your system and frequently asked questions can be found     at: https://wiki.debian.org/LTS

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - 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. (CVE-2019-8921)

Note that Nessus relies on the presence of the package as reported by the vendor.

The version of bluez installed on the remote host is prior to 5.44-7. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2023-2309 advisory.

    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. (CVE-2019-8922)

  - 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 authenticated pairing with the responding device using     the correct Passkey for the pairing session. The attack methodology determines the Passkey value one bit     at a time. (CVE-2020-26558)

  - Improper access control in BlueZ may allow an authenticated user to potentially enable information     disclosure via adjacent access. (CVE-2021-0129)

  - 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. (CVE-2021-3658)

  - 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-2021-43400)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

  - BlueZ before 5.59 allows physically proximate attackers to obtain sensitive information because     profiles/audio/avrcp.c does not validate params_len. (CVE-2022-39176)

  - BlueZ before 5.59 allows physically proximate attackers to cause a denial of service because malformed and     invalid capabilities can be processed in profiles/audio/avdtp.c. (CVE-2022-39177)
