Description

CVE-2016-0718 : Out-of-bounds read flaw

An out-of-bounds read flaw was found in the way Expat processed certain input.

A remote attacker could send specially crafted XML that, when parsed by an

application using the Expat library, would cause that application to crash or,

possibly, execute arbitrary code with the permission of the user running the

application.

Solution

Run 'yum update expat' to update your system.
