Synopsis

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

Description

The remote SUSE Linux SLES15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2022:0237-1 advisory.

This update for the Linux Kernel 4.12.14-150_72 fixes several issues.

The following security issues were fixed:

- CVE-2018-25020: Fixed an issue in the BPF subsystem in the Linux kernel mishandled situations with a long jump over an instruction sequence where inner instructions require substantial expansions into multiple BPF instructions, leading to an overflow. (bsc#1193575)
- CVE-2020-3702: Fixed a bug which could be triggered with specifically timed and handcrafted traffic and cause internal errors in a WLAN device that lead to improper layer 2 Wi-Fi encryption with a consequent possibility of information disclosure. (bsc#1191193)
- CVE-2021-42739: The firewire subsystem had a buffer overflow related to drivers/media/firewire/firedtv- avc.c and drivers/media/firewire/firedtv-ci.c, because avc_ca_pmt mishandled bounds checking (bsc#1184673).

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 kernel-livepatch-4_12_14-150_72-default and / or kernel-livepatch-4_12_14-150_75-default packages.
