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


Synopsis :

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

Description :

Multiple flaws were found in the way RPM parsed package file headers.
An attacker could create a specially-crafted RPM package that, when
its package header was accessed, or during package signature
verification, could cause an application using the RPM library (such
as the rpm command line tool, or the yum and up2date package managers)
to crash or, potentially, execute arbitrary code. (CVE-2012-0060,
CVE-2012-0061, CVE-2012-0815)

insufficient validation of region tags (BZ 744858)

improper validation of header contents total size in headerLoad() (BZ
798585)

incorrect handling of negated offsets in headerVerifyInfo() (BZ
744104)
