"The remote host is affected by the vulnerability described in GLSA-202209-16 (BlueZ: Multiple Vulnerabilities)

  - 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)

  - 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-2021-3588)

  - 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-2022-0204)

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