IN NO EVENT WILL SUN MICROSYSTEMS, INC. BE LIABLE FOR ANY LOST REVENUE, PROFIT OR DATA, OR FOR DIRECT, SPECIAL, INDIRECT, CONSEQUENTIAL, INCIDENTAL OR PUNITIVE DAMAGES HOWEVER CAUSED AND REGARDLESS OF ANY THEORY OF LIABILITY ARISING OUT OF THE USE OF OR INABILITY TO USE THE INFORMATION CONTAINED IN THIS SECURITY BULLETIN, EVEN IF SUN MICROSYSTEMS, INC.

A vulnerability in certain versions of the Java Runtime Environment may allow malicious Java code to execute unauthorized commands. However, permission to execute at least one command must have been granted in order for this vulnerability to be exploited. Since no permission is granted by default, the circumstances necessary to exploit this vulnerability are relatively rare. In the Java Development Kit 1.1.x (JDK(TM) 1.1.x) (browsers included), an applet must be signed to have execute permission (signed applets may execute anything in JDK 1.1.x.)
This issue may or may not affect other vendors' Java technology implementations which are derived from Sun's JDK source base. Sun has notified and made the remedy available to its Java licensees.
To the best of Sun's knowledge, Netscape Navigator(TM) and Microsoft Internet Explorer are not exposed to this vulnerability.
Sun recommends that you upgrade to the latest JDK and JRE releases listed in section 3 of this bulletin.
2. Affected Releases
The following releases are affected:
