Hi Kavitha -
In general, specialized security work is outside of the scope of the
/educational mission/ at OSGeoLive project.
ASLR is a security layer ? from Google search..
"Address Space Layout Randomization (*ASLR*) is a computer security
technique which involves randomly positioning the base address of an
executable and the position of libraries, heap, and stack, in a
process's address space"
Security is a concern at OSGeoLive, but not the primary concern. If you
seek direct consulting hours, please consider a time+money budget to
bring in additional skillsets.
If you find a solution, please do not hesitate to share the results with
the GDAL project and Ubuntu upstream, for better specialized security in
the future.
others may have different resources for you on this topic
best regards --Brian

Hi All,
We are trying to compile the gdal 2.3.2 source with ASLR . But we are
seeing the
Elf file type as EXEC (Executable file) instead DYN.
Please help us whether gdal build is supported the compilation with
"-Fpie -pie -fPIC".
Steps which we followed:
cp gdalDevKits/gdal-2.3.2.tar.gz .
tar -xvf gdal-2.3.2.tar.gz
cd gdal-2.3.2
env CFLAGS="-Fpie -pie -fPIC" ./configure
make install
cd /usr/local/bin
readelf -l gdaltransform
Elf file type is EXEC (Executable file)
Entry point 0x40
Thanks,
Kavitha
