openSUSE-SU-2026:21166-1

This update for nano fixes the following issues:

Changes in nano:

• Update to version 9.1:

  • When searching, the viewport is placed snug left where possible.
  • The ability to read and write files in old Mac format (a lone carriage return as line ending) was removed.
  • The ^T toggle between WhereIs and GotoLine was dropped.
  • Fix backups that were missing or had a wrong timestamp when --backup is active.
  • On a crash or kill, a .save file is no longer chmodded or chowned to the base file's permissions and owner.
  • The history code now creates the ~/.local directory with limited access rights (boo#1263437; the referenced CVE-2026-40556 was rejected upstream).
  • M-Ins and M-Del have become rebindable.

• GNU nano 9.0:

  • When the cursor almost goes offscreen to the right, all lines are now scrolled sideways together, by just the amount needed to keep the cursor in view. Use --solosidescroll or 'set solosidescroll' to get back the old, jerky, single-line horizontal scrolling.
  • The viewport can be scrolled sideways (in steps of one tabsize) with M-< and M->. See man nanorc if M-< and M-> should switch between buffers (as they did earlier).
  • M-Left, M-Right, M-Up, and M-Down have become rebindable.
  • Stopping the recording of a macro immediately after starting it cancels the recording and leaves an existing macro in place.
  • Feature toggles no longer break a chain of ^K cuts or M-6 copies, except the M-K cut-from-cursor toggle.
  • With --mouse and --indicator, one can click in the scrollbar area to roughly navigate within the buffer.
  • CVE-2026-6843: format string vulnerability leads to denial of service (boo#1262643)
  • create the ~/.local directory with limited access rights (CVE-2026-6842 boo#1263022, CVE-2026-40556 boo#1263437)

• GNU nano 8.7.1:

  • fix build against glibc-2.43 (boo#1258260)

• GNU nano 8.7:

  • At the Execute prompt, preceding the command with two pipe symbols allows implementing a copy-to-clipboard feature in nanorc on terminals that support OSC 52. See doc/sample.nanorc
