Subject: [PATCH] remove executable flag from .dyninst_heap section
|
|
|
|
This prevents the library/object with this code from having a segment violates
|
|
the W^X security property for segments as the current setting resulted in
|
|
segment with both the WRITE and EXECUTE flags set. The function
|
|
mark_heaps_exec() restores execute protection to just the heap arrays.
