Synopsis

The remote Amazon Linux AMI host is missing a security update.

Description

The get_rock_ridge_filename function in fs/isofs/rock.c in the Linux kernel before 4.5.5 mishandles NM (aka alternate name) entries containing \\0 characters, which allows local users to obtain sensitive information from kernel memory or possibly have unspecified other impact via a crafted isofs filesystem. (CVE-2016-4913)

Run 'yum update kernel' to update your system.
