critical Nessus Plugin ID 167726

Language:

Synopsis

The remote SUSE host is missing one or more security updates.

Description

The remote SUSE Linux SLED15 / SLED_SAP15 / SLES15 / SLES_SAP15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2022:3981-1 advisory.

- 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.

Solution

Update the affected bluez, bluez-cups, bluez-deprecated and / or libbluetooth3 packages.
