Advisory: Specially crafted addresses can execute arbitrary code

Severity: Extremely Severe

Problem Description

   If a malicious page redirects Opera to a specially crafted address
   (URL), it can cause Opera to crash. Given sufficient address content,
   the crash could cause execution of code controlled by the attacking
   page.

Opera's Response

   Opera Software has released Opera 9.60, where this issue has been
   fixed.

Advisory: Java applets can be used to read sensitive information

Severity: Highly Severe

Problem Description

   Once a Java applet has been cached, if a page can predict the cache
   path for that applet, it can load the applet from the cache, causing
   it to run in the context of the local machine. This allows it to read
   other cache files on the computer or perform other normally more
   restrictive actions. These files could contain sensitive information,
   which could then be sent to the attacker.

Opera's Response

   Opera Software has released Opera 9.60, where this issue has been
   fixed.
