opening a malicious web page, an attacker could perform cross-site
scripting attacks. (CVE-2008-0416)
Various flaws were discovered in the JavaScript engine. By tricking
a user into opening a malicious web page, an attacker could escalate

containing Basic Authentication credentials with empty usernames. An
attacker could exploit this vulnerability to perform cross-site request
forgery attacks. (CVE-2008-1238)
Peter Brodersen and Alexander Klink reported that default the setting in

Gregory Fleischer discovered that web content fetched via the jar
protocol could use Java LiveConnect to connect to arbitrary ports on
the user's machine due to improper parsing in the Java plugin. If a
