"The remote SUSE Linux SLES12 host has a package installed that is affected by multiple vulnerabilities as referenced in
the SUSE-SU-2023:3083-1 advisory.
- A vulnerability was found in the HCI sockets implementation due to a missing capability check in
net/bluetooth/hci_sock.c in the Linux Kernel. This flaw allows an attacker to unauthorized execution of
management commands, compromising the confidentiality, integrity, and availability of Bluetooth
communication. (CVE-2023-2002)
- A use after free issue was discovered in driver/firewire in outbound_phy_packet_callback in the Linux
Kernel. In this flaw a local attacker with special privilege may cause a use after free problem when
queue_event() fails. (CVE-2023-3159)
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
