Update:

AST-2013-001 (CVE-2013-2685):
  Not applicable to either Stable or Testing/Unstable:
  new code not included yet even in 1.8.

AST-2013-002 (CVE-2013-2686):
  Applies to Testing/Unstable but not to Stable:
  Testing/Unstable: see patch from Upstream. Stable: httpd code does not
  read HTTP POST variables.

AST-2013-003 (CVE-2013-2264):
  Applies to both Testing and Unstable.
  Testing/Unstable: see patch from Upstream. Stable: Patch backported.

For Unstable/Testing I include two other simple bug fixes. Both trivial
backports from later 1.8.x reevisions.
