This may allow a man-in-the- middle attacker to redirect connections and intercept user credentials or other sensitive information. This issue is addressed by blacklisting the fraudulent certificates. Note: For Mac OS X systems, this issue is addressed with Security Update 2011-002. For Windows systems, Safari relies on the certificate store of the host operating system to determine if an SSL server certificate is trustworthy. Applying the update described in Microsoft Knowledge Base Article 2524375 will cause Safari to regard these certificates as untrusted. The article is available at http://support.microsoft.com/kb/2524375 libxslt Available for: iOS 3.0 through 4.3.1 for iPhone 3GS and later, iOS 3.1 through 4.3.1 for iPod touch (3rd generation) and later, iOS 3.2 through 4.3.1 for iPad Impact: Visiting a maliciously crafted website may lead to the disclosure of addresses on the heap Description: libxslt's implementation of the generate-id() XPath function disclosed the address of a heap buffer. Visiting a maliciously crafted website may lead to the disclosure of addresses on the heap, which may aid in bypassing address space layout randomization protection. This issue is addressed by generating an ID based on the difference between the addresses of two heap buffers.
