Commencing with version 6.0, if the process is a so-known as shielded method, the KernelCallbackTable pointer is to start with put to double obligation given that the UserSharedInfoPtr. Just although connecting, it turns into a aspect-channel for getting a SHAREDINFO structure straight from WIN32K.SYS. Home windows XP and Home windows Server 2003 acquired into some kind of tussle about using the past of your previously reserved dwords. The ExecuteOptions certainly are Utilized in the early releases of both of those.

If this transformation was enthusiastic by thoughts of safety, it absolutely was even worse than pointless because the kernel does not merely Adhere to the FastPebLockRoutine and FastPebUnlockRoutine ideas within the PEB but calls through them to execute (what it hopes for being) NTDLL code at its person-mode tackle. Will not miss that no matter what is there receives executed with ring 0 privilege. This trick which is plainly also clever for anyone’s superior was finished for Model five.two in 2003, which certainly is Anyone’s achieve, however it absolutely was retained even for the very long-lived past service pack of Variation five.1 in 2008, apparently with out Microsoft at any time warning anyone of it. From the incredibly earliest versions, it experienced considerable use. Amid the reasons the kernel would access the PEB in ways that desired synchronisation with access by other threads (probably in person method) had been such things as the kernel allocating from and liberating to the method heap. Even as late as version five.one, this execution of person-manner code with kernel-mode prvilege was nevertheless becoming carried out for your exported (and documented) function RtlQueryRegistryValues to extend ecosystem variables whose names are uncovered involving percent symptoms in registry knowledge which has the REG_EXPAND_SZ kind. Can it really be that Microsoft was never termed out for this grotesqueness? Offset (x86) Offset (x64) Definition Variations 0x28 0x50 ULONG EnvironmentUpdateCount;
