We need to verify that the `result_size` is not larger than our buffer,
and also should make sure that the `len` which is passed to
`isc_vax_integer()` has a permissible value; otherwise we bail out.

We can no longer export from git.php.net, and apparently exporting from
Github is not supported. We apply a quick fix to export from the local
clone by default, still leaving an option to export from some other
repo. This is, unfortunately, a minor BC break in a security release.

Like `mail()` and `mb_send_mail()`, `imap_mail_compose()` must prevent
header injection. For maximum backward compatibility, we still allow
header folding for general headers, and still accept trailing line
breaks for address lists.
When no test paths are specified this shows up when 'make test' is used on a PECL extension without specifying tests to run (or in php-src too, I guess...)

That bug report originally was about `parse_url()` misbehaving, but the
security aspect was actually only regarding `FILTER_VALIDATE_URL`.
Since the changes to `parse_url_ex()` apparently affect userland code
which is relying on the sloppy URL parsing[1], this alternative
restores the old parsing behavior, but ensures that the userinfo is
checked for correctness for `FILTER_VALIDATE_URL`.
[1] <https://github.com/php/php-src/commit/5174de7cd33c3d4fa591c9c93859ff9989b07e8c#commitcomment-45967652>
To avoid that `parse_url()` returns an erroneous host, which would be
valid for `FILTER_VALIDATE_URL`, we make sure that only userinfo which
is valid according to RFC 3986 is treated as such.
For consistency with the existing url parsing code, we use ctype
functions, although that is not necessarily correct.
In MariaDB-10.4.3 EXPIRE passwords where supported for
MariaDB. This only behaves like MySQL when the system
variable disconnect_on_expired_passwords=1.
MariaDB if there was no password it could not be considered
expired. So the test is adjusted to use actual passwords.
(MariaDB commit a94b20a8e0d9e64eeaabdaaa7a3e03fcdb8a686e)
The error codes produced my MariaDB are different
however still conforming to the SQL specification.
Closes GH-6480.
MySQL removed RENAME DATABASE in 18300001c1dbbfddf9a0adcbaeea68956102bdd0
(Sept 2007, 5.1.23). As this briefest existance is very insignificant lets remove it.
It also breaks when testing against MariaDB.
As the alternate path in this test covers all supported MySQL and MariaDB
versions and a signifant portion of unsupported versions lets keep it simple.
Closes GH-6459.
As of commit 81b2f3e[1], `parse_url()` accepts URLs with a zero port,
but does not report that port, what is wrong in hindsight.
Since the port number is stored as `unsigned short` there is no way to
distinguish between port zero and no port. For BC reasons, we thus
introduce `parse_url_ex2()` which accepts an output parameter that
allows that distinction, and use the new function to fix the behavior.
The introduction of `parse_url_ex2()` has been suggested by Nikita.

Unless `SQLGetData()` returns `SQL_SUCCESS` or `SQL_SUCCESS_WITH_INFO`,
the `StrLen_or_IndPtr` output argument is not guaranteed to be properly
set. Thus we handle retrieval failure other than `SQL_ERROR` by
yielding `false` for those column values and raising a warning.
Closes GH-6281.
This reverts commit bf6873a18e.
CVE-2020-26159 is bogus; the "bug" was apparently a false positive
reported by Coverity, and the "fix" apparently wrong, see
<https://github.com/kkos/oniguruma/issues/221>.
Closes GH-6357.
libxml2 has no particular issues parsing HTML strings with NUL bytes;
these just cause truncation of the current text content, but parsing
continues generally. Since `::loadHTMLFile()` already supports NUL
bytes, `::loadHTML()` should as well.
Note that this is different from XML, which does not allow any NUL
bytes.
Closes GH-6368.
A recent bug fix regarding symlinks claimed:
> After resolving reparse points, the path still may be a reparse
> point; in that case we have to resolve that reparse point as well.
While that is basically correct, some reparse points may point to
inaccessible system folders (e.g. `IO_REPARSE_TAG_DEDUP` points to
"\System Volume Information"). Since we don't know details about
arbitrary reparse points, and are mainly interested in nested symlinks,
we take a step back, and only resolve `IO_REPARSE_TAG_SYMLINK` for now.
Close GH-6354.
`ADD_EXTENSION_DEP()` relies on the `PHP_<extname>` config variables to
be set to `"yes"`, and since the standard and date extension are always
enabled, we define the respective variables uncoditionally.
Closes GH-6383.
"Uninitialized" here means that the object was created ordinarily
-- no constructor skipping involved. Most tidy methods seem to
handle this fine, but these three need to be guarded.
libc-client expects `TYPEMESSAGE` with an explicit subtype of `RFC822`
to have a `nested.msg` (otherwise there will be a segfault during
free), but not to have any `contents.text.data` (this will leak
otherwise).
Closes GH-6345.
In libc-client 2007f `data` is declared as `unsigned char *`; there may
be variants which declare it as `void *`, but in any case picky
compilers may warn about a pointer type mismatch in the conditional
(and error with `-W-error`), so we're adding a `char *` cast for good
measure.
The original fix for that bug[1] broke the formerly working composition
of message/rfc822 messages, which results in a segfault when freeing
the message body now. While `imap_mail_compose()` does not really
support composition of meaningful message/rfc822 messages (although
libc-client appears to support that), some code may still use this to
compose partial messages, and using string manipulation to create the
final message.
The point is that libc-client expects `TYPEMESSAGE` with an explicit
subtype of `RFC822` to have a `nested.msg` (otherwise there will be a
segfault during free), but not to have any `contents.text.data` (this
will leak otherwise).
