Miscalculated SizeOfImage value
Recently putty project (<a href="http://www.putty.org/">http://www.putty.org/</a>) switched to building with clang
and lld instead of Microsoft's toolchain. Their latest released PE 32 bit
binary (<a href="https://the.earth.li/~sgtatham/putty/latest/w32/putty.exe">https://the.earth.li/~sgtatham/putty/latest/w32/putty.exe</a>) seems to has
faulty SizeOfImage value on the PE header, if you check the actual size of the
PE image just after mapping it on the memory it does not add up to the header
value. This bug causes packers like UPX to crash while trying to parse the PE
file. I sent a email to the putty team and they sad it should be about the lld
linker.</pre>
