Description:
Marc Schoenefeld has reported a weakness in Opera, which can be exploited by malicious people to disclose some system information.
Opera accesses the JRE (Java Runtime Environment) directly instead of using the Java plugin. The problem is that the "accessClassInPackage" permission is improperly given to the "sun.*" packages, which can be exploited by a malicious untrusted applet to gain knowledge of the full path to the currently logged in user's username and installation directory.
Successful exploitation requires that Sun Java is installed and that the permission "accessClassInPackage sun.*" is given in "Opera.policy" (default).
The weakness has been reported in version 7.54. Other versions may also be affected.
Solution:
Update to version 7.54u1.
