Amazon Linux AMI : curl (ALAS-2017-806)

Medium Nessus Plugin ID 97896

Synopsis

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

Description

libcurl's implementation of the printf() functions triggers a buffer overflow when doing a large floating point output. If there are any application that accepts a format string from the outside without necessary input filtering, it could allow remote attacks. This flaw does not exist in the command line tool.

Solution

Run 'yum update curl' to update your system.
