Subject: [PATCH] vi: Fix recalling lines starting with whitespace (re:
5eeeed06)
@jghub reports:
> if for some reason a command is entered with leading whitespace,
> the leading whitespace is preserved in the history file (in
> ksh93u+, too). such commands can be recalled from history in 93u+
> without problem, both, in vi and emacs mode.
>
> but in 93u+m such entries are simply ignored when using vi-mode
> (set -o vi), i.e. the k and j commands skip over such entries.
> emacs mode still works just fine.
Analysis: the blankline() function in vi.c and emacs.c is used to
check for whitespace up to the cursor position. This is used for
tab completion and fullscreen editor invocation, where that is
okay, and for history recall, where that should be checking the
entire line instead.
In emacs.c this was not really a problem because arrowing up (or
^P) positions the cursor to the end of the line anyway. But in vi,
arrowing up (or 'k') positions the cursor at the beginning.
src/cmd/ksh93/edit/vi.c:
- Amend blankline() with an 'uptocursor' argument. If nonzero, it
checks the current line for whitespace up to the cursor position,
otherwise it checks the entire line.
- Pass uptocursor==0 to blankline() for history recall and 1 for
tab completion.
src/cmd/ksh93/edit/emacs.c:
- Apply the same change here for consistency, even though it's
perhaps not really necessary. If ever a form of recall is added
that doesn't position the cursor at the end, then that won't
introduce this bug there.
Thanks to @pghvlaans for input into the fix.

Subject: [PATCH] jobs: change p_job variable type from short to int (#763)
This change addresses an issue where ksh has undefined behavior
when the number of jobs exceeds `2^15 - 1` (32767), which is the
maximum value for a `short`. The short integer overflow happened in
jobs.c, line 1210.

It was committed prematurely and still broken on most systems.
src/cmd/ksh93/sh/fault.c: sh_done():
- Revert changes.
src/cmd/ksh93/sh/jobs.c: job_wait():
- Do not set sh.chldexitsig in the first place if the signal is
SIGPIPE and we're in a real subshell.
This workaround passes all the tests I can throw at it.

Subject: [PATCH] Fix segfault upon SIGWINCH after 'stty -echo' (re: 83630f9d)
After disabling terminal echo (stty -echo), ksh either crashes or
writes garbage to the terminal upon resizing the terminal window.
This also affects the use of ksh for 'M-x shell' in emacs.
Analysis: The ed_viread and ed_emacsread functions declare buffers
as local (automatic) variables that are destroyed when the function
exits, but other functions then access then using globally declared
pointers in structs of type Edit_t, Emacs_t and Vi_t.
However, upon 'stty -echo', the terminal cannot be set to raw mode,
so the tty_raw call fails in these two functions. At this point,
they fall back to ed_read and return, never initialising those
pointers. But the SIGWINCH handling routine in edit.c calls redraw
routines that depend on those pointers being valid -- and crash.
src/cmd/ksh93/edit/emacs.c: ed_emacsread():
- Attempt to set raw mode before doing or initialising anything
else: move the tty_raw call and ed_read fallback to the start.
This avoids superfluous init and makes more sense.
- Before returning, reset all global pointers that point to this
function call's local variables to NULL. (To aid with this, use a
'done' goto label and an 'r' variable for the return code.) This
ensures these pointers will be either valid or NULL, making
debugging easier, as well as allowing the code to check for this.
src/cmd/ksh93/edit/vi.c: ed_viread():
- Same changes as for emacs.
src/cmd/ksh93/edit/edit.c: ed_read():
- If e_prompt is NULL, that is now an indication that ed_emacsread
or ed_viread are not being used because the tty_raw call failed;
therefore, skip SIGWINCH handling, except for flushing the notify
buffer (see 667034ff). This fixes the crash.
Thanks to @nickpapadonis for the report.

Subject: [PATCH] Fix arbitrary command execution/code injection bugs (#866)
* Security patch part 1
Never use $SHELL or sh.shpath when executing shebang-less scripts
- sh_ntfork(): Removed a misguided optimization that causes ksh to
run scripts without a shebang using the binary pointed to by
either $SHELL or sh.shpath. This has a few problems:
- The shell in sh.shpath or more disastrously in $SHELL has
no guarantee of being identical to the currently running
copy of ksh93 or even existing at all, so using either is
not only bogus, but potentially dangerous.
- The optimization has no ability to pass down the current
POSIX mode status to the script.
- It's only activated for virtual subshells, resulting in
arbitrarily different behavior depending on whether or
not we're in a virtual subshell.
- It does some weird stuff with /dev/fd that seems superfluous,
and also lacks any SHOPT_DEVFD if directive. (Additionally,
if it did have one, that stat(2) would likely become mere
dead code and a waste of context switches.)
The optimization was probably intended to be used for running a
shebang-less script via posix_spawn, which is ostensibly faster
than fork. But this simply isn't possible without risking running
the shebang-less script in a shell environment different from
the current one. (If ksh were updated by the package manager
while ksh is still running, this optimization would cause the
script to run via the new version, rather than the currently
running older version.) The optimization is unfixable by design,
and as such must be removed to ensure correct behavior.
* Security patch part 2 (re: bae02c39)
rm setuid script code leading to arbitrary command execution
Changes:
- Delete code for setuid scripts on "Solaris 2.5+" because it
allows for arbitrary command execution. One millisecond you think
you're launching ksh, the next you're at the mercy of a hijacker.
Example:
SHELL=/bin/ppmflash /bin/ksh -l /dev/fd/0 < <(true)
MANPATH: usage: MANPATH flashfactor [ppmfile]
flashfactor: 0.0 = original picture, 1.0 = total whiteout
The pathshell() code doesn't *seem* to be vulnerable to privilege
escalation, but who knows (cf. CVE-2019-14868; this might need its
own CVE 2025. Maybe pathshell() should be scrapped entirely???)
- Add fickle but functional regression test (you may need to pass
KSH=/bin/ksh or some such to get it to fail against vulnerable
versions of ksh). The test uses a login shell via the -l option,
but the bug *does not* need a login shell. See:
https://github.com/ksh93/ksh/issues/874#issue-3128739066
Modify the execveat reproducer to pass along environ (which
could include a hijacked SHELL), and you're in for a BAD time.
Maybe the deleted code (introduced sometime within the period of 1995
and 1999) was relevant to some Solaris-specific use case or something.
Maybe the erasure even causes an incompatibility. But that code must
go; it's far too dangerous to execv whatever the hell pathshell gives
us during **init**. (Need I bring CVE-2019-14868 back to remembrance
again? This bug has similarities to that one.)
FWIW, all of the regression tests in the ksh and modernish suites pass
with this patch applied.
* Security patch part 3
Delete pathshell() and replace uses of it with safer equivalents
This function is a dangerous attack vector that ought not remain
in the code base. The value returned by astconf() is doubtless
safer than what is returned by pathshell().
* Other changes
The libast pathprog function and prog feature test are now unused,
and are removed.

Subject: [PATCH] Fix segfault on starting ksh with no TERM env var (#723)
This commit fixes a crash that prevented ksh from starting up in
single user mode on DragonFlyBSD and NetBSD.
src/cmd/ksh93/edit/edit.c:
- Make sure the np node for $TERM is not null before checking for
an export attribute.
