By enticing a user to add a bookmark with an overlong title, an attacker may trigger the issue which may lead to an unexpected application termination or arbitrary code execution. This update addresses the issue by performing proper bounds checking. This issue does not affect Mac OS X systems. WebKit CVE-ID: CVE-2007-2408 Available for: Mac OS X v10.4.9 or later, Windows XP or Vista Impact: Visiting a malicious website may allow Java applets to load and run even when Java is disabled Description: Safari provides an "Enable Java" preference, which when unchecked should prevent the loading of Java applets. By default, Java applets are allowed to be loaded. Navigating to a maliciously crafted web page may allow a Java applet to be loaded without checking the preference. This update addresses the issue through a stricter check of the "Enable Java" preference. Credit to Rhys Kidd and Scott Wilde for reporting this issue. WebKit CVE-ID: CVE-2007-3742 Available for: Mac OS X v10.4.9 or later, Windows XP or Vista Impact: Look-alike characters in a URL could be used to masquerade a website Description: The International Domain Name (IDN) support and Unicode fonts embedded in Safari could be used to create a URL which contains look-alike characters. These could be used in a malicious web site to direct the user to a spoofed site that visually appears to be a legitimate domain. This update addresses the issue by through an improved domain name validity check. Credit to Tomohito Yoshino of Business Architects Inc. for reporting this issue. WebKit CVE-ID: CVE-2007-3944 Available for: Mac OS X v10.4.9 or later, Windows XP or Vista Impact: Viewing a maliciously crafted web page may lead to arbitrary code execution Description: Heap buffer overflows exist in the Perl Compatible Regular Expressions (PCRE) library used by the JavaScript engine in Safari.

This update addresses the issues by performing additional validation of JavaScript regular expressions.
