Multiple stack-based buffer overflows in ovalarmsrv in HP OpenView Network Node Manager (OV NNM) 7.51, and possibly 7.01, 7.50, and 7.53, allow remote attackers to execute arbitrary code via a long (1) REQUEST_SEV_CHANGE (aka number 47), (2) REQUEST_SAVE_STATE (aka number 61), or (3) REQUEST_RESTORE_STATE (aka number 62) request to TCP port 2954.

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.

Unspecified vulnerability in HP OpenView Network Node Manager (OV NNM) 6.20, 6.4x, 7.01, 7.50, and 7.51 allows remote authenticated users to access certain privileged "facilities" via unspecified vectors.

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.

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.

Multiple unspecified vulnerabilities in HP OpenView Network Node Manager (OV NNM) 6.20, 6.4x, 7.01, and 7.50 allow remote attackers to gain privileged access, execute arbitrary commands, or create arbitrary files via unknown vectors.

Multiple unknown vulnerabilities in OpenView Network Node Manager (OV NNM) 6.2, 6.4, 7.01, and 7.50 allow attackers to cause a denial of service or execute arbitrary code.

Unknown vulnerability in HP OpenView Network Node Manager (NMM) 6.2 through 6.4, and 7.01 through 7.50, allows remote attackers to cause a denial of service.
