CFNetwork in Apple iOS before 5.0.1 and Mac OS X 10.7 before 10.7.2 does not properly parse URLs, which allows remote attackers to trigger visits to unintended web sites, and transmission of cookies to unintended web sites, via a crafted (1) http or (2) https URL.

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 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.
