The HTTP_Request_Parser method in the HTTP Transport component in IBM WebSphere Application Server (WAS) 6.0.2 before 6.0.2.31 allows remote attackers to cause a denial of service (controller 0C4 abend and application hang) via a long HTTP Host header, related to "storage overlay" on the stack and a "parse failure."

Unspecified vulnerability in the serveServletsByClassnameEnabled feature in IBM WebSphere Application Server (WAS) 6.0 through 6.0.2.25, 6.1 through 6.1.0.14, and 5.1.1.x before 5.1.1.18 has unknown impact and attack vectors.

The web container in IBM WebSphere Application Server (WAS) before 6.0.2.21, and 6.1.x before 6.1.0.9, sends response data intended for a different request in certain circumstances after a closed connection error, which might allow remote attackers to obtain sensitive information.
