Oracle Java Soundbank Stack Buffer Overflow



Java Runtime Environment (JRE) is a platform that supports the execution of programs that are developed using the Java programming language. It is available for multiple platforms, including Windows, Linux and MacOS. The JRE platform also supports Java Applets which can be loaded from Web pages. For more information, visit the link shown below.


Remote exploitation of a buffer overflow vulnerability in Oracle's Java Runtime Environment could allow an attacker to execute arbitrary code with the privileges of the current user.

During the parsing of specially crafted Soundbank resource, an overly long length value can lead to a stack buffer overflow condition within the Java Runtime Environment. The length value may cause a pointer to reference a location outside the bounds of a fixed sized stack buffer, a memory write is then performed by dereferencing the pointer. This condition may allow a remote attacker to subvert execution control and execute arbitrary code.


Exploitation of this vulnerability results in the execution of arbitrary code with the privileges of the current user. In order to exploit this vulnerability, a user must load a web page containing a specially crafted Java applet. An attacker typically accomplishes this via social engineering or injecting content into compromised, trusted sites. Typical social engineering attacks will pass URLs as part of instant messages or electronic mail.


Java SE is vulnerable. JDK and JRE 6 Update 25 and earlier, JDK 5.0 Update 29 and earlier and SDK 1.4.2_31 and earlier are vulnerable.


It is possible to disable the Java plugin in Internet Explorer, Firefox, Safari, Opera and Google Chrome.
