Synopsis

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

Description

The remote SUSE Linux SLES12 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2023:0420-1 advisory.

 The SUSE Linux Enterprise 12 SP2 kernel was updated to receive various security and bugfixes.


 The following security bugs were fixed:

 - CVE-2018-9517: Fixed possible memory corruption due to a use after free in pppol2tp_connect (bsc#1108488).
 - CVE-2022-3564: Fixed use-after-free in l2cap_core.c of the Bluetooth component (bsc#1206073).
 - CVE-2022-3643: Fixed reset/abort/crash via netback from VM guest (bsc#1206113).
 - CVE-2022-42895: Fixed an information leak in the net/bluetooth/l2cap_core.c's l2cap_parse_conf_req() which can be used to leak kernel pointers remotely (bsc#1205705).
 - CVE-2022-42896: Fixed a use-after-free vulnerability in the net/bluetooth/l2cap_core.c's l2cap_connect() and l2cap_le_connect_req() which may have allowed code execution and leaking kernel memory (respectively) remotely via Bluetooth (bsc#1205709).
 - CVE-2022-4662: Fixed incorrect access control in the USB core subsystem that could lead a local user to crash the system (bsc#1206664).
 - CVE-2022-47929: Fixed NULL pointer dereference bug in the traffic control subsystem (bsc#1207237).
 - CVE-2023-23454: Fixed a type-confusion in the CBQ network scheduler (bsc#1207036).
 - CVE-2023-23455: Fixed a denial of service inside atm_tc_enqueue in net/sched/sch_atm.c because of type confusion (non-negative numbers can sometimes indicate a TC_ACT_SHOT condition rather than valid classification results) (bsc#1207125).


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

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