Synopsis

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

Description

The remote SUSE Linux SLED12 / SLED_SAP12 / SLES12 / SLES_SAP12 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2022:3718-1 advisory.

- In BlueZ 5.42, an out-of-bounds read was observed in le_meta_ev_dump function in tools/parser/hci.c source file. This issue exists because 'subevent' (which is used to read correct element from 'ev_le_meta_str' array) is overflowed. (CVE-2016-9803)

- 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 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 and / or libbluetooth3 packages.
