[jbossseam-issues] [JBoss JIRA] Commented: (JBSEAM-1322) MutlipartRequest parser occasionally throws ArrayIndexOutOfBoundsException

MutlipartRequest parser occasionally throws ArrayIndexOutOfBoundsException -------------------------------------------------------------------------- Key: JBSEAM-1322 URL: http://jira.jboss.com/jira/browse/JBSEAM-1322 Project: JBoss Seam Issue Type: Bug Components: Core Affects Versions: 1.2.1.GA, 1.2.0.GA Environment: Windows Vista, Java 1.6u1, JBoss Seam 1.2.1, JBoss AS 4.0.5.GA Reporter: ROB b Assigned To: Shane Bryzak During an upload, the MultipartRequest checkSequence function does not to proper boundary checking on function parameters. It will occasionally (rarely actually) throw an ArrayIndexOutOfBoundsException at the high end due to the +1 offset when accessing the data array. I'm not actually sure why this +1 is there and was wondering if somehow it was a mistake. This class is a little hard to follow, so I'm not sure how everything works, but the function description seems to indicate that it is checking for the end of a byte array at a specific location which is 0-indexed, but the +1 would seem to indicate otherwise. The following exception gets thrown: java.lang.ArrayIndexOutOfBoundsException: 2048 at org.jboss.seam.web.MultipartRequest.checkSequence(MultipartRequest.java:466) at org.jboss.seam.web.MultipartRequest.parseRequest(MultipartRequest.java:333) at org.jboss.seam.web.MultipartRequest.getParam(MultipartRequest.java:507) at org.jboss.seam.web.MultipartRequest.getParameter(MultipartRequest.java:558) at org.apache.myfaces.context.servlet.RequestParameterMap.getAttribute(RequestParameterMap.java:39) at org.apache.myfaces.context.servlet.AbstractAttributeMap.get(AbstractAttributeMap.java:87) at com.sun.facelets.tag.ui.UIDebug.debugRequest(UIDebug.java:119) at com.sun.facelets.FaceletViewHandler.restoreView(FaceletViewHandler.java:305) at org.ajax4jsf.framework.ViewHandlerWrapper.restoreView(ViewHandlerWrapper.java:116) at org.ajax4jsf.framework.ajax.AjaxViewHandler.restoreView(AjaxViewHandler.java:147) at org.apache.myfaces.lifecycle.LifecycleImpl.restoreView(LifecycleImpl.java:141) at org.apache.myfaces.lifecycle.LifecycleImpl.execute(LifecycleImpl.java:66) at javax.faces.webapp.FacesServlet.service(FacesServlet.java:137) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:252) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:173) at org.jboss.seam.web.SeamFilter$FilterChainImpl.doFilter(SeamFilter.java:63) at org.jboss.seam.web.ExceptionFilter.doFilter(ExceptionFilter.java:57) at org.jboss.seam.web.SeamFilter$FilterChainImpl.doFilter(SeamFilter.java:49) at org.jboss.seam.debug.hot.HotDeployFilter.doFilter(HotDeployFilter.java:60) at org.jboss.seam.web.SeamFilter$FilterChainImpl.doFilter(SeamFilter.java:49) at org.jboss.seam.web.RedirectFilter.doFilter(RedirectFilter.java:45) at org.jboss.seam.web.SeamFilter$FilterChainImpl.doFilter(SeamFilter.java:49) at org.jboss.seam.web.MultipartFilter.doFilter(MultipartFilter.java:74) at org.jboss.seam.web.SeamFilter$FilterChainImpl.doFilter(SeamFilter.java:49) at org.jboss.seam.web.SeamFilter.doFilter(SeamFilter.java:84) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:202) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:173) at org.ajax4jsf.framework.ajax.xmlfilter.BaseXMLFilter.doXmlFilter(BaseXMLFilter.java:96) at org.ajax4jsf.framework.ajax.xmlfilter.BaseFilter.doFilter(BaseFilter.java:220) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:202) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:173) at org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:96) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:202) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:173) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:213) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:178) at org.jboss.web.tomcat.security.SecurityAssociationValve.invoke(SecurityAssociationValve.java:175) at org.apache.catalina.authenticator.AuthenticatorBase.invoke(AuthenticatorBase.java:432) at org.jboss.web.tomcat.security.JaccContextValve.invoke(JaccContextValve.java:74) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:126) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:105) at org.jboss.web.tomcat.tc5.jca.CachedConnectionValve.invoke(CachedConnectionValve.java:156) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:107) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:148) at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:869) at org.apache.coyote.http11.Http11BaseProtocol$Http11ConnectionHandler.processConnection(Http11BaseProtocol.java:664) at org.apache.tomcat.util.net.PoolTcpEndpoint.processSocket(PoolTcpEndpoint.java:527) at org.apache.tomcat.util.net.MasterSlaveWorkerThread.run(MasterSlaveWorkerThread.java:112) at java.lang.Thread.run(Unknown Source)
