Description

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2019:3967 advisory.

- kernel: Inifinite loop vulnerability in mm/madvise.c:madvise_willneed() function allows local denial of service (CVE-2017-18208)
