Looks like public symbols contain this structure starting with Win7,
so we can deduce what it looked like in Win2003.
Note that our previous definition was missing a second ULONG at the
end, which can be seen in the SeQueryInfoToken kmtest -- if you
allocated only sizeof(AUX_ACCESS_DATA), the test would crash with
a 4 byte buffer overflow.
This reverts 8479509 commit which pretty much does nothing at all (the captured pointer is NULL within the stack of the function has no effect outside of the function). My mistake, sorry.
Whenever a captured security property such as privilege or SID is released, we must not have such captured property point at random address in memory but rather we must assign it as NULL after it's been freed from pool memory. This avoids potential double-after-free situations where we might release a buffer twice.
This is exactly the case with token filtering.
In SeCaptureLuidAndAttributesArray we must ensure that we don't go onto a potential integer overflow scenario by checking against the maximum limit threshold the kernel states. In addition, write an explicit name macro for the value.
Fix a wrong returned datatype of the function, as SepSinglePrivilegeCheck calls the internal private SepPrivilegeCheck function which returns a BOOLEAN value.
- Change INIT_FUNCTION and INIT_SECTION to CODE_SEG("INIT") and DATA_SEG("INIT") respectively
- Remove INIT_FUNCTION from function prototypes
- Remove alloc_text pragma calls as they are not needed anymore
