ITS ADVISORY NUMBER:
2013-008

DATE(S) ISSUED:
02/04/2013

SUBJECT:
Multiple Vulnerabilities In Oracle Java Could Allow Remote Code Execution

OVERVIEW:

Multiple vulnerabilities have been discovered in Oracle Java Runtime Environment (JRE) that can lead to remote code execution. The Java Runtime Environment is used to enhance the user experience when visiting websites and is installed on most desktops and servers. This vulnerability may be exploited if a user visits or is redirected to a specifically crafted web page. Successful exploitation of these vulnerabilities could allow an attacker to gain the same privileges as the JRE application. Depending on the privileges associated with the application, an attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.

SYSTEM AFFECTED:

  • Oracle Java SE JDK and JRE 7 Update 11 and earlier
  • Oracle Java SE JDK and JRE 6 Update 38 and earlier
  • Oracle Java SE and JRE 5.0 Update 38 and earlier
  • Oracle Java SE SDK and JRE 1.4.2_40 and earlier
  • Oracle Java SE JavaFX 2.2.4 and earlier

RISK:

Government:

  • Large and medium government entities: High
  • Small government entities: High

Businesses:

  • Large and medium business entities: High
  • Small business entities: High

Home users: High

DESCRIPTION:
Multiple vulnerabilities have been discovered in Oracle Java Runtime Environment that can lead to remote code execution. In order to exploit these vulnerabilities, an attacker must first create a specially crafted web page designed to leverage this issue. When the web page is visited, the code is run in the context of the affected application. Successful exploitation of these vulnerabilities could result in an attacker gaining the same privileges as the JRE application. Depending on the privileges associated with the application, an attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.

RECOMMENDATIONS:
We recommend the following actions be taken: 

  • Apply the patch from Oracle, after appropriate testing.
  • Run all software as a non-privileged user (one without administrative privileges) to diminish the effects of a successful attack.
  • Remind users not to visit un-trusted websites or follow links provided by unknown or un-trusted sources.
  • Remind users not to open e-mail attachments from unknown users or suspicious e-mails from trusted sources.
