Process Monitor 1.22 does not properly validate certain parameters to System Service Descriptor Table (SSDT) function handlers, which allows local users to cause a denial of service (crash) and possibly gain privileges via unspecified kernel SSDT hooks for Windows Native API functions including (1) NtCreateKey, (2) NtDeleteValueKey, (3) NtLoadKey, (4) NtOpenKey, (5) NtQueryValueKey, (6) NtSetValueKey, and (7) NtUnloadKey.

RegMon 7.04 does not properly validate certain parameters to System Service Descriptor Table (SSDT) function handlers, which allows local users to cause a denial of service (crash) and possibly gain privileges via kernel SSDT hooks to the (1) NtCreateKey and (2) NtOpenKey Windows Native API functions.

Buffer overflow in Sysinternals Process Explorer 9.23, and other versions before 9.25, allows local users to execute arbitrary code via a long CompanyName field in the VersionInfo information in a running process.

NtRegmon before 6.12 allows local users to cause a denial of service (crash), while NtRegmon is running, via invalid pointers to hook functions such as ZwSetQueryValue.
