Amazon Linux AMI : php55 Multiple Vulnerabilities (ALAS-2014-314)

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


Synopsis :

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

Description :

Fine Free file before 5.17 allows context-dependent attackers to cause
a denial of service (infinite recursion, CPU consumption, and crash)
via a crafted indirect offset value in the magic of a file.

A flaw was found in the way the file utility determined the type of
Portable Executable (PE) format files, the executable format used on
Windows. A malicious PE file could cause the file utility to crash or,
potentially, execute arbitrary code.

The gdImageCrop function in ext/gd/gd.c in PHP 5.5.x before 5.5.9 does
not check return values, which allows remote attackers to cause a
denial of service (application crash) or possibly have unspecified
other impact via invalid imagecrop arguments that lead to use of a
NULL pointer as a return value.
