high Nessus Plugin ID 106330

Synopsis

The remote Red Hat host is missing one or more security updates for kernel.

Description

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2018:0151 advisory.

- kernel: local privesc in key management (CVE-2015-8539)

- hw: cpu: speculative execution bounds-check bypass (CVE-2017-5753)

- kernel: keyctl_set_reqkey_keyring() leaks thread keyrings (CVE-2017-7472)

- kernel: NULL pointer dereference due to KEYCTL_READ on negative key (CVE-2017-12192)
