Apple Safari allows remote attackers to cause a denial of service (browser crash) via JavaScript that matches a regular expression against a long string, as demonstrated using /(.)*/.

Format string vulnerability in iMovie HD 6.0.3, and Safari in Apple Mac OS X 10.4 through 10.4.10, allows remote user-assisted attackers to cause a denial of service (crash) via format string specifiers in a filename, which is not properly handled when calling the NSRunCriticalAlertPanel Apple AppKit function.

WebCore on Apple Mac OS X 10.3.9 and 10.4.10, as used in Safari, does not properly parse HTML comments in TITLE elements, which allows remote attackers to conduct cross-site scripting (XSS) attacks and bypass some XSS protection schemes by embedding certain HTML tags within an HTML comment.

Safari in Mac OS X 10.3.9 and 10.4.2, when rendering Rich Text Format (RTF) files, can directly access URLs without performing the normal security checks, which allows remote attackers to execute arbitrary commands.

Safari in Mac OS X 10.3.9 and 10.4.2 submits forms from an XSL formatted page to the next page that is browsed by the user, which causes form data to be sent to the wrong site.

Safari in WebKit in Mac OS X 10.4 to 10.4.2 directly accesses URLs within PDF files without the normal security checks, which allows remote attackers to execute arbitrary code via links in a PDF file.
