Unspecified vulnerability in ovtopmd in HP OpenView Network Node Manager (OV NNM) 7.01, 7.51, and 7.53 allows remote attackers to cause a denial of service via unknown vectors, a different vulnerability than CVE-2008-3536, CVE-2008-3537, and CVE-2008-3544. NOTE: due to insufficient details from the vendor, it is not clear whether this is the same as CVE-2008-1853.

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.

Unspecified vulnerability in ovalarmsrv in HP OpenView Network Node Manager (OV NNM) 7.01, 7.51, and 7.53 allows remote attackers to cause a denial of service via unknown vectors, a different vulnerability than CVE-2008-3536.

Unspecified vulnerability in ovalarmsrv in HP OpenView Network Node Manager (OV NNM) 7.01, 7.51, and 7.53 allows remote attackers to cause a denial of service via unknown vectors, a different vulnerability than CVE-2008-3537.

The ovtopmd service in HP OpenView Network Node Manager (OV NNM) 7.51, 7.53, and possibly other versions allows remote attackers to cause a denial of service (exit) by sending a 0x36 packet (exit request).

Directory traversal vulnerability in OpenView5.exe in HP OpenView Network Node Manager (OV NNM) 7.01, 7.51, and 7.53 allows remote attackers to read arbitrary files via directory traversal sequences in the Action parameter.

ovalarmsrv in HP OpenView Network Node Manager (OV NNM) 7.51, 7.53, and possibly other versions allows remote attackers to cause a denial of service (hang) via certain requests that do not provide all required arguments.

ovalarmsrv in HP OpenView Network Node Manager (OV NNM) 7.51, 7.53, and possibly other versions allows remote attackers to cause a denial of service (crash) via certain requests that specify a large number of sub-arguments, which triggers a NULL pointer dereference due to memory allocation failure.

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.

Stack-based buffer overflow in ovwparser.dll in HP OpenView Network Node Manager (OV NNM) 7.53, 7.51, and earlier allows remote attackers to execute arbitrary code via a long URI in an HTTP request processed by ovas.exe, as demonstrated by a certain topology/homeBaseView request.
