Synopsis :

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

Description :

A heap-based buffer overflow flaw was found in the way libpng
processed compressed chunks in PNG image files. An attacker could
create a specially-crafted PNG image file that, when opened, could
cause an application using libpng to crash or, possibly, execute
arbitrary code with the privileges of the user running the
application.
