APPLE-SA-2011-07-20-1 Safari 5.1 and Safari 5.0.6

Safari 5.1 and Safari 5.0.6 are now available and address the
following:

CFNetwork
Available for: Windows 7, Vista, XP SP2 or later
Impact: Visiting a maliciously crafted website may lead to a cross-
site scripting attack
Description: In certain situations, Safari may treat a file as HTML,
even if it is served with the 'text/plain' content type. This may
lead to a cross-site scripting attack on sites that allow untrusted
users to post text files. This issue is addressed through improved
handling of 'text/plain' content.
CVE-ID
CVE-2010-1420 : Hidetake Jo working with Microsoft Vulnerability
Research (MSVR), Neal Poole of Matasano Security

CFNetwork
Available for: Windows 7, Vista, XP SP2 or later
Impact: Authenticating to a maliciously crafted website may lead to
arbitrary code execution
Description: The NTLM authentication protocol is susceptible to a
replay attack referred to as credential reflection. Authenticating to
a maliciously crafted website may lead to arbitrary code execution.
To mitigate this issue, Safari has been updated to utilize protection
mechanisms recently added to Windows. This issue does not affect Mac
OS X systems.
CVE-ID

CFNetwork
Available for: Windows 7, Vista, XP SP2 or later
Impact: A root certificate that is disabled may still be trusted
Description: CFNetwork did not properly validate that a certificate
was trusted for use by a SSL server. As a result, if the user had
marked a system root certificate as not trusted, Safari would still
accept certificates signed by that root. This issue is addressed
through improved certificate validation. This issue does not affect
Mac OS X systems.
