Subject: [PATCH] patch 9.0.0579: using freed memory when 'tagfunc' wipes out
buffer
Problem: Using freed memory when 'tagfunc' wipes out buffer that holds
'complete'.
Solution: Make a copy of the option. Make sure cursor position is valid.

Subject: [PATCH] patch 9.0.2068: [security] overflow in :history
Problem: [security] overflow in :history
Solution: Check that value fits into int
The get_list_range() function, used to parse numbers for the :history
and :clist command internally uses long variables to store the numbers.
However function arguments are integer pointers, which can then
overflow.
Check that the return value from the vim_str2nr() function is not larger
than INT_MAX and if yes, bail out with an error. I guess nobody uses a
cmdline/clist history that needs so many entries... (famous last words).
It is only a moderate vulnerability, so impact should be low.

Subject: [PATCH] patch 9.0.1833: [security] runtime file fixes
Problem: runtime files may execute code in current dir
Solution: only execute, if not run from current directory
The perl, zig and ruby filetype plugins and the zip and gzip autoload
plugins may try to load malicious executable files from the current
working directory. This is especially a problem on windows, where the
current directory is implicitly in your $PATH and windows may even run a
file with the extension `.bat` because of $PATHEXT.
So make sure that we are not trying to execute a file from the current
directory. If this would be the case, error out (for the zip and gzip)
plugins or silently do not run those commands (for the ftplugins).
This assumes, that only the current working directory is bad. For all
other directories, it is assumed that those directories were
intentionally set to the $PATH by the user.

Subject: [PATCH] patch 9.0.2108: [security]: overflow with count for :s
command
Problem: [security]: overflow with count for :s command
Solution: Abort the :s command if the count is too large
If the count after the :s command is larger than what fits into a
(signed) long variable, abort with e_value_too_large.
Adds a test with INT_MAX as count and verify it correctly fails.
It seems the return value on Windows using mingw compiler wraps around,
so the initial test using :s/./b/9999999999999999999999999990 doesn't
fail there, since the count is wrapping around several times and finally
is no longer larger than 2147483647. So let's just use 2147483647 in the
test, which hopefully will always cause a failure

Problem: [security]: overflow in ex address parsing
Solution: Verify that lnum is positive, before substracting from

[security]: overflow in ex address parsing
When parsing relative ex addresses one may unintentionally cause an
overflow (because LONG_MAX - lnum will overflow for negative addresses).
So verify that lnum is actually positive before doing the overflow
check.

Subject: [PATCH] patch 9.0.2112: [security]: overflow in shift_line
Problem: [security]: overflow in shift_line
Solution: allow a max indent of INT_MAX
[security]: overflow in shift_line
When shifting lines in operator pending mode and using a very large
value, we may overflow the size of integer. Fix this by using a long
variable, testing if the result would be larger than INT_MAX and if so,
indent by INT_MAX value.
Special case: We cannot use long here, since on 32bit architectures (or
on Windows?), it typically cannot take larger values than a plain int,
so we have to use long long count, decide whether the resulting
multiplication of the shiftwidth value * amount is larger than INT_MAX
and if so, we will store INT_MAX as possible larges value in the long
long count variable.
Then we can safely cast it back to int when calling the functions to set
the indent (set_indent() or change_indent()). So this should be safe.
Add a test that when using a huge value in operator pending mode for
shifting, we will shift by INT_MAX

Subject: [PATCH] patch 9.0.2121: [security]: use-after-free in ex_substitute
Problem: [security]: use-after-free in ex_substitute
Solution: always allocate memory
closes: #13552
A recursive :substitute command could cause a heap-use-after free in Vim
(CVE-2023-48706).
The whole reproducible test is a bit tricky, I can only reproduce this
reliably when no previous substitution command has been used yet
(which is the reason, the test needs to run as first one in the
test_substitute.vim file) and as a combination of the `:~` command
together with a :s command that contains the special substitution atom `~\=`
which will make use of a sub-replace special atom and calls a vim script
function.
There was a comment in the existing :s code, that already makes the
`sub` variable allocate memory so that a recursive :s call won't be able
to cause any issues here, so this was known as a potential problem
already. But for the current test-case that one does not work, because
the substitution does not start with `\=` but with `~\=` (and since
there does not yet exist a previous substitution atom, Vim will simply
increment the `sub` pointer (which then was not allocated dynamically)
and later one happily use a sub-replace special expression (which could
then free the `sub` var).
The following commit fixes this, by making the sub var always using
allocated memory, which also means we need to free the pointer whenever
we leave the function. Since sub is now always an allocated variable,
we also do no longer need the sub_copy variable anymore, since this one
was used to indicated when sub pointed to allocated memory (and had
therefore to be freed on exit) and when not.

Subject: [PATCH 2156/2205] patch 9.0.1969: [security] buffer-overflow in
trunc_string()
Problem: buffer-overflow in trunc_string()
Solution: Add NULL at end of buffer
Currently trunc_string() assumes that when the string is too long,
buf[e-1] will always be writeable. But that assumption may not always be
true. The condition currently looks like this
else if (e + 3 < buflen)
[...]
else
{
// can't fit in the "...", just truncate it
buf[e - 1] = NUL;
}
but this means, we may run into the last else clause with e still being
larger than buflen. So a buffer overflow occurs.
So instead of using `buf[e - 1]`, let's just always
truncate at `buf[buflen - 1]` which should always be writable.

overflow to the caller function.

Subject: [PATCH] runtime(tar): improve the error detection
Do not rely on the fact, that the last line matches warning, error,
inappropriate or unrecognized to determine if an error occurred. It
could also be a file, contains such a keyword.
So make the error detection slightly more strict and only assume an
error occured, if in addition to those 4 keywords, also a space matches
(this assumes the error message contains a space), which luckily on Unix
not many files match by default.
The whole if condition seems however slightly dubious. In case an error
happened, this would probably already be caught in the previous if
statement, since this checks for the return code of the tar program.
There may however be tar implementations, that do not set the exit code
for some kind of error (but print an error message)? But let's keep this
check for now, not many people have noticed this behaviour until now, so
it seems to work reasonably well anyhow.
related: #6425
fixes: #13489
