Synopsis

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

Description

The remote SUSE Linux SLES15 / SLES_SAP15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2021:2427-1 advisory.

The SUSE Linux Enterprise 15 SP3 kernel was updated to receive various security and bugfixes.

The following security bugs were fixed:

- CVE-2021-22555: Fixed an heap out-of-bounds write in net/netfilter/x_tables.c that could allow local provilege escalation. (bsc#1188116)
- CVE-2021-33624: Fixed a bug which allows unprivileged BPF program to leak the contents of arbitrary kernel memory (and therefore, of all physical memory) via a side-channel. (bsc#1187554)
- CVE-2021-0605: Fixed an out-of-bounds read which could lead to local information disclosure in the kernel with System execution privileges needed. (bsc#1187601)
- CVE-2021-0512: Fixed a possible out-of-bounds write which could lead to local escalation of privilege with no additional execution privileges needed. (bsc#1187595)
- CVE-2020-26558: Fixed a flaw in the Bluetooth LE and BR/EDR secure pairing that could permit a nearby man-in-the-middle attacker to identify the Passkey used during pairing. (bnc#1179610)
- CVE-2021-34693: Fixed a bug in net/can/bcm.c which could allow local users to obtain sensitive information from kernel stack memory because parts of a data structure are uninitialized. (bsc#1187452)
- CVE-2021-0129: Fixed an improper access control in BlueZ that may have allowed an authenticated user to potentially enable information disclosure via adjacent access. (bnc#1186463)
- CVE-2020-36386: Fixed an out-of-bounds read in hci_extended_inquiry_result_evt. (bsc#1187038)
- CVE-2020-24588: Fixed a bug that could allow an adversary to abuse devices that support receiving non- SSP A-MSDU frames to inject arbitrary network packets. (bsc#1185861 bsc#1185863)
- CVE-2021-33909: Fixed an out-of-bounds write in the filesystem layer that allows to andobtain full root privileges. (bsc#1188062)
- CVE-2021-3609: Fixed a race condition in the CAN BCM networking protocol which allows for local privilege escalation. (bsc#1187215)
- CVE-2020-36385: Fixed a use-after-free flaw in ucma.c which allows for local privilege escalation.
(bsc#1187050)
- CVE-2021-33200: Fix leakage of uninitialized bpf stack under speculation. (bsc#1186484)

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