EMC Legato Networker Remote Exec Service Stack Overflow Vulnerabilities

These vulnerabilities allow remote attackers to execute arbitrary code on vulnerable installations of EMC Networker. Authentication is not required to exploit this vulnerability. The specific flaws exist in the Networker Remote Exec Service, nsrexecd.exe. The location of this service is available by querying the SUNRPC portmapper on TCP port 111 for service #0x5f3e1, version 1. When supplying a long invalid subcmd to a poll or a kill request, an exploitable stack overflow vulnerability can occur within a call to sprintf().
