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. The manipulation of the argument cap_len 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.

An update of the bluez package has been released.

The version of bluez installed on the remote CBL Mariner 2.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2022-3563 advisory.

  - 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. The manipulation     of the argument cap_len 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. (CVE-2022-3563)

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

The remote Ubuntu 16.04 LTS / 18.04 LTS / 20.04 LTS / 22.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6809-1 advisory.

    It was discovered that BlueZ could be made to dereference invalid memory. An attacker could possibly use     this issue to cause a denial of service. This issue only affected Ubuntu 22.04 LTS. (CVE-2022-3563)

    It was discovered that BlueZ could be made to write out of bounds. If a user were tricked into connecting     to a malicious device, an attacker could possibly use this issue to cause a denial of service or execute     arbitrary code. (CVE-2023-27349)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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

The remote Redhat Enterprise Linux 8 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - kernel: Authvalue leak in Bluetooth Mesh Provisioning (CVE-2020-26559)

  - bluez: BlueZ 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)

  - Pairing in Bluetooth Core v5.2 and earlier may permit an unauthenticated attacker to acquire credentials     with two pairing devices via adjacent access when the unauthenticated user initiates different pairing     methods in each peer device and an end-user erroneously completes both pairing procedures with the MITM     using the confirmation number of one peer as the passkey of the other. An adjacent, unauthenticated     attacker could be able to initiate any Bluetooth operation on either attacked device exposed by the     enabled Bluetooth profiles. This exposure may be limited when the user must authorize certain access     explicitly, but so long as a user assumes that it is the intended remote device requesting permissions,     device-local protections may be weakened. (CVE-2020-10134)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

The remote Redhat Enterprise Linux 9 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - kernel: impersonation attack in Bluetooth Mesh Provisioning (CVE-2020-26560)

  - bluez: BlueZ 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)
