Integer signedness error in ovspmd.exe in HP OpenView Network Node Manager (OV NNM) 8.01, and 7.53 and earlier, allows remote attackers to cause a denial of service (daemon crash) or execute arbitrary code via a long request to TCP port 8886 that begins with a certain negative integer, which passes a signed comparison and triggers a heap-based buffer overflow.

Multiple stack-based buffer overflows in HP OpenView Network Node Manager (OV NNM) 6.41, 7.01, and 7.51 allow remote attackers to execute arbitrary code via unspecified long arguments to (1) ovlogin.exe, (2) OpenView5.exe, (3) snmpviewer.exe, and (4) webappmon.exe, as demonstrated via a long Action parameter to OpenView5.exe.

HP OpenView Network Node Manager 6.2 through 7.50 allows remote attackers to execute arbitrary commands via shell metacharacters in the (1) node parameter to connectedNodes.ovpl, (2) cdpView.ovpl, (3) freeIPaddrs.ovpl, and (4) ecscmg.ovpl.

ovtopmd in HP OpenView Network Node Manager (OV NNM) 6.41, 7.01, and 7.51 allows remote attackers to cause a denial of service (crash) via a crafted TCP request that triggers an out-of-bounds memory access.

Unspecified vulnerability in HP OpenView Network Node Manager (OV NNM) 6.20, 6.4x, 7.01, and 7.50 allows remote attackers to execute arbitrary commands via unknown vectors.

Memory leak in HP OpenView Network Node Manager (NNM) 6.2 and 6.4 allows remote attackers to cause a denial of service (memory exhaustion) via crafted TCP packets.

Unspecified vulnerability in HP OpenView Network Node Manager (OV NNM) 6.20, 6.4x, 7.01, and 7.50 allows remote attackers to read arbitrary files via unknown vectors.

Cross-site scripting (XSS) vulnerability in HP OpenView Network Node Manager (OV NNM) 6.41, 7.01, and 7.51 allows remote attackers to inject arbitrary web script or HTML via unspecified vectors.
