Sun Java WebStart contains a stack buffer overflow, which can allow a remote, unauthenticated attacker to execute arbitrary code on a vulnerable system.
Sun Java WebStart is a technology for launching stand-alone Java applications. On Microsoft Windows systems, Java WebStart is provided by the program javaws.exe, which is included with the Sun Java Runtime Environment (JRE). Java WebStart operates by processing a JNLP file, which is an XML document that contains information about the Java application to execute. The Sun JRE installer configures Internet Explorer and Netscape Navigator to automatically open JNLP files without any user interaction.
Java WebStart contains a stack buffer overflow in the handling of JNLP files. This vulnerability can be exploited to execute arbitrary code as the result of opening a specially-crafted JNLP file, which can occur as the result of viewing a malicious web site. We have received reports that this vulnerability is being actively exploited.
By convincing a user to open a specially-crafted JNLP file, a remote, unauthenticated attacker may be able to execute arbitrary code on a vulnerable system. This may occur as the result of viewing a specially-crafted web page.
