high Nessus Plugin ID 160104

Language:

Synopsis

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

Description

The remote SUSE Linux SLES12 host has a package installed that is affected by multiple vulnerabilities as referenced in the SUSE-SU-2022:1322-1 advisory.

- A use-after-free flaw was found in the Linux kernel's FUSE filesystem in the way a user triggers write().
This flaw allows a local user to gain unauthorized access to data from the FUSE filesystem, resulting in privilege escalation. (CVE-2022-1011)

- A flaw was found in the Linux kernel in net/netfilter/nf_tables_core.c:nft_do_chain, which can cause a use-after-free. This issue needs to handle 'return' with proper preconditions, as it can lead to a kernel information leak problem caused by a local, unprivileged attacker. (CVE-2022-1016)

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 kgraft-patch-4_12_14-122_77-default package.
