Synopsis
The remote Amazon Linux AMI host is missing a security update.
Description
A vulnerability was found in libpq, the default PostgreSQL client library where libpq failed to properly reset its internal state between connections. If an affected version of libpq were used with 'host' or 'hostaddr' connection parameters from untrusted input, attackers could bypass client-side connection security features, obtain access to higher privileged connections or potentially cause other impact through SQL injection, by causing the PQescape() functions to malfunction.(CVE-2018-10915)
Solution
Run 'yum update postgresql93' to update your system.
Run 'yum update postgresql94' to update your system.
