Stack-based buffer overflow in the NetWorker Remote Exec Service (nsrexecd.exe) in EMC Software NetWorker 7.x.x allows remote attackers to execute arbitrary code via a (1) poll or (2) kill request with a "long invalid subcmd."

nsrd.exe in EMC Legato NetWorker 7.1.x before 7.1.4 and 7.2.x before 7.2.1.Build.314, and other products such as Sun Solstice Backup (SBU) 6.0 and 6.1 and StorEdge Enterprise Backup Software (EBS) 7.1 through 7.2L, allows remote attackers to cause a denial of service (nsrd service crash) via a malformed RPC request to RPC program number 390109, which triggers a null dereference.

Multiple heap-based buffer overflows in EMC Legato NetWorker 7.1.x before 7.1.4 and 7.2.x before 7.2.1.Build.314, and other products such as Sun Solstice Backup (SBU) 6.0 and 6.1 and StorEdge Enterprise Backup Software (EBS) 7.1 through 7.2L, allow remote attackers to execute arbitrary code or cause a denial of service (unresponsive application) via malformed RPC packets to (1) RPC program number 390109 (nsrd.exe) and (2) RPC program number 390113 (nsrexecd.exe).
