This script is Copyright (C) 2013-2014 Tenable Network Security, Inc.


Synopsis :

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

Description :

libtiff did not properly convert between signed and unsigned integer
values, leading to a buffer overflow. An attacker could use this flaw
to create a specially crafted TIFF file that, when opened, would cause
an application linked against libtiff to crash or, possibly, execute
arbitrary code. (CVE-2012-2088)

Multiple integer overflow flaws, leading to heap-based buffer
overflows, were found in the tiff2pdf tool. An attacker could use
these flaws to create a specially crafted TIFF file that would cause
tiff2pdf to crash or, possibly, execute arbitrary code.
(CVE-2012-2113)
