Synopsis

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

Description

The remote SUSE Linux SLED15 / SLES15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2021:2325-1 advisory.

The SUSE Linux Enterprise 15 SP2 kernel was updated to receive various security and bugfixes.

The following security bugs were fixed:

- CVE-2021-3573: Fixed an UAF vulnerability in function that can allow attackers to corrupt kernel heaps and adopt further exploitations. (bsc#1186666)
- 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-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-2021-34693: 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 improper access control in BlueZ that may have allowed an authenticated user to potentially enable information disclosure via adjacent access (bnc#1186463).
- CVE-2020-36385: Fixed a use-after-free via the ctx_list in some ucma_migrate_id situations where ucma_close is called (bnc#1187050).
- CVE-2020-26558: Fixed Bluetooth LE and BR/EDR secure pairing in Bluetooth Core Specification 2.1 (bnc#1179610, bnc#1186463).
- CVE-2020-36386: Fixed an out-of-bounds read issue in hci_extended_inquiry_result_evt (bnc#1187038).

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.

Solution

Update the affected packages.
