high Nessus Plugin ID 97022

Language:

Synopsis

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

Description

A stack overflow vulnerability was found in _nss_dns_getnetbyname_r.
On systems with nsswitch configured to include 'networks: dns' with a privileged or network-facing service that would attempt to resolve user-provided network names, an attacker could provide an excessively long network name, resulting in stack corruption and code execution.

Solution

Run 'yum update glibc' to update your system.
