The Data Security component in Apple iOS before 5 and Apple TV before 4.4 does not properly restrict use of the MD5 hash algorithm within X.509 certificates, which makes it easier for man-in-the-middle attackers to spoof servers or obtain sensitive information via a crafted certificate.

The remote host is running a version of Mac OS X 10.x that is prior to version 10.9. The newer version contains multiple security-related fixes for the following components :

  - Application Firewall
  - App Sandbox
  - Bluetooth
  - CFNetwork
  - CFNetwork SSL
  - Console
  - CoreGraphics
  - curl
  - dyld
  - IOKitUser
  - IOSerialFamily
  - Kernel
  - Kext Management
  - LaunchServices
  - Libc
  - Mail Accounts
  - Mail Header Display
  - Mail Networking
  - OpenLDAP
  - perl
  - Power Management
  - python
  - ruby
  - Security
  - Security - Authorization
  - Security - Smart Card Services
  - Screen Lock
  - Screen Sharing Server
  - syslog
  - USB

The mobile device is running a version of iOS that is prior to version 5.0. Version 5.0 contains numerous security-related fixes for the following vulnerabilities :

  - Apple iOS Calendar Synchronization SSL Certificate     Validation Information Disclosure Vulnerability     (CVE-2011-3253)

  - Apple iOS Calendar Cross-Site Scripting Vulnerability     (CVE-2011-3254)

  - Apple iOS CFNetwork Information Disclosure Vulnerability     (CVE-2011-3255)

  - Apple iOS Mail Cookie Synchronization Validation     Information Disclosure Vulnerability (CVE-2011-3257)

  - An information disclosure vulnerability, known as BEAST,     exists in the SSL 3.0 and TLS 1.0 protocols due to a     flaw in the way the initialization vector (IV) is     selected when operating in cipher-block chaining (CBC)     modes. A man-in-the-middle attacker can exploit this     to obtain plaintext HTTP header data, by using a     blockwise chosen-boundary attack (BCBA) on an HTTPS     session, in conjunction with JavaScript code that uses     the HTML5 WebSocket API, the Java URLConnection API,     or the Silverlight WebClient API.
