Vendor description This Security Alert addresses security issues CVE-2013-1493 (US-CERT VU#688246) and another vulnerability affecting Java running in web browsers. These vulnerabilities are not applicable to Java running on servers, standalone Java desktop applications or embedded Java applications. They also do not affect Oracle server-based software. These vulnerabilities may be remotely exploitable without authentication, i.e., they may be exploited over a network without the need for a username and password.
