Re: [PATCH 0/1] MR4742: server: Allow PROCESS_QUERY_INFORMATION on LIMITED handle.

[eric pouech (＠epo)]

the fix can't be in server/handle.c (the access bits meaning depends on the object you're considering...)

looking at server/process.c:process_map_access: setting PROCESS_QUERY_INFORMATION always set PROCESS_QUERY_LIMITED_INFORMATION (but not the other way around)

so you need to figure out where an access is tested against PROCESS_QUERY_INFORMATION while it should be against PROCESS_QUERY_LIMITED_INFORMATION

hint: VirtualQueryEx -> NtQueryVirtualMemory -> get_basic_memory_info -> which queues an APC (APC_VIRTUAL_QUERY)
