Description: A vulnerability has been reported in Sun Java Web Start, which can be exploited by malicious people to compromise a user's system. The vulnerability is caused due to a boundary error within the Java Web Start component (javaws.exe) when processing JNLP files. This can be exploited to cause a stack-based buffer overflow via a specially crafted JNLP file with an overly long codebase attribute. Successful exploitation allows execution of arbitrary code e.g. when a user visits a malicious website. The vulnerability is reported in the following versions: * JRE and JDK 6 Update 1 and earlier * JRE and JDK 5 Update 11, and earlier Solution: Apply updates. JRE/JDK 5 Update 12: http://java.sun.com/javase/downloads/index_jdk5.jsp JRE/JDK 6 Update 2: http://java.sun.com/javase/downloads/index.jsp Provided and/or discovered by: Daniel Soeder, eEye Digital Security The vendor also credits Brett Moore.
