Multiple vulnerabilities have been identified in EMC Legato Networker, which could be exploited by remote attackers to cause a denial of service or take complete control of an affected system. These issues are caused by stack overflow errors in the Networker Remote Exec Service (nsrexecd.exe) when processing a poll or kill request with an overly long and invalid subcmd (sent to the SUNRPC portmapper on TCP port 111 for service #0x5f3e1, version 1), which could be exploited by remote unauthenticated attackers to crash an affected service or execute arbitrary code.
