Description of problem:
Network accessible programs should be PIEs for security reasons.  I'll attach a
minimum patch to make sshd (and none of the other programs) a PIE.

Version-Release number of selected component (if applicable):

How reproducible:

Better patch

Better use Jakub's patch which also adds various optimizations.
Comment 3 Tomas Mraz 2005-02-04 11:33:52 EST
The minimal patch is maintainable and could/(should?) be applied. The
Jakub's one is highly invasive and it would require too much work when
rebasing to newer versions.
Comment 4 Tomas Mraz 2005-02-21 11:02:23 EST
Sorry ignore my previous comment - currently in rawhide the complete
OpenSSH is already built with PIE. However a question is if the PIE
linkage shouldn't be limited to sshd.
