Loading vulnerability…
Apache Tomcat contains an error-handling flaw in the doRead method affecting versions 4.1.32 through 4.1.34 and 5.5.10 through 5.5.20. For a specific read error condition, doRead fails to return -1 as required. This can cause request-body handling to continue incorrectly and POST content associated with one HTTP request to be sent as content for a different request, disclosing prior-request data across request boundaries.
