Safari CVE-ID: CVE-2007-4680 Available for: Windows XP or Vista Impact: A remote attacker may be able to cause an untrusted certificate to appear trusted Description: An issue exists in the validation of certificates. A man-in-the-middle attacker may be able to direct the user to a legitimate site with a valid SSL certificate, then re-direct the user to a spoofed web site that incorrectly appears to be trusted. This could allow user credentials or other information to be collected. This update addresses the issue through improved validation of certificates. This issue is addressed for Mac OS X in Security Update 2007-008, and is incorporated into Mac OS X v10.4.11 and Mac OS X v10.5 or later.

This update addresses the issue by returning an error on any proxy error, instead of returning the proxy-supplied data. This issue has already been addressed in Mac OS X 10.5.2, and in Security Update 2008-002 for Mac OS X 10.4.11 systems.

Safari CVE-ID: CVE-2008-1001 Available for: Windows XP or Vista Impact: Visiting a maliciously crafted website may result in cross- site scripting Description: A cross-site scripting issue exists in Safariis error page. By enticing a user to open a maliciously crafted URL, an attacker may cause the disclosure of sensitive information. This update addresses the issue by performing additional validation of URLs. This issue does not affect Mac OS X systems. Credit to Robert Swiecki of Google Information Security Team for reporting this issue.

Safari CVE-ID: CVE-2008-1002 Available for: Mac OS X v10.4.11, Mac OS X v10.5.2, Windows XP or Vista Impact: Visiting a maliciously crafted website may result in cross- site scripting Description: A cross-site scripting issue exists in the processing of [removed] URLs. Enticing a user to visit a maliciously crafted web page could allow the execution of JavaScript in the context of another site. This update addresses the issue by performing additional validation of [removed] URLs. Credit to Robert Swiecki of Google Information Security Team for reporting this issue.

WebCore CVE-ID: CVE-2008-1003 Available for: Mac OS X v10.4.11, Mac OS X v10.5.2, Windows XP or Vista Impact: Visiting a maliciously crafted website may result in cross- site scripting Description: An issue exists with the handling of web pages that have explicitly set the document.domain property. This could lead to a cross-site scripting attack in sites that set the document.domain property, or between HTTP and HTTPS sites with the same document.domain. This update addresses the issue by improving same- origin checks. Credit to Adam Barth and Collin Jackson of Stanford University for reporting this issue.

WebCore CVE-ID: CVE-2008-1004 Available for: Mac OS X v10.4.11, Mac OS X v10.5.2, Windows XP or Vista Impact: Using Web Inspector on a maliciously crafted website may result in cross-site scripting Description: An issue in Web Inspector allows a page being inspected to escalate its privileges by injecting script that will run in other domains and read the useris file system.
