Amazon Linux AMI : rpm Package Header Parsing Error (ALAS-2011-14)

This script is Copyright (C) 2013 Tenable Network Security, Inc.


Synopsis :

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

Description :

The RPM Package Manager (RPM) is a command line driven package
management system capable of installing, uninstalling, verifying,
querying, and updating software packages.

Multiple flaws were found in the way the RPM library parsed package
headers. An attacker could create a specially-crafted RPM package
that, when queried or installed, would cause rpm to crash or,
potentially, execute arbitrary code. (CVE-2011-3378)

Note: Although an RPM package can, by design, execute arbitrary code
when installed, this issue would allow a specially-crafted RPM package
to execute arbitrary code before its digital signature has been
verified. Package downloads from the Red Hat Network remain secure due
to certificate checks performed on the secure connection.
