Two issues:
1) We should not modify the object when we pass invalid values
2) We should reset the properties to their default value otherwise we
get a UAF.

Closes GH-15248.
When using libedit/readline integration in phpdbg:
./configure --with-libedit --enable-phpdbg-readline
EOF makes editline write prompt again in local console mode. For
example, this can be noticed when reading phpt test files from STDIN and
running phpdbg:
./sapi/cli/php run-tests.php sapi/phpdbg
Closes GH-13199
This is an old bug, but this is pretty easy to fix.
It's basically applying the same fix as I did for e878b9f.
Reported by YuanchengJiang.
Closes GH-15143.
Instead of fixing up temporaries count in between observer steps, just apply the additional temporary in the two affected observer steps.
Closes GH-14018.
For top-level anonymous type definition we never store the declaration anywhere
else nor the type anywhere else.
The declaration keeps owning the type and it goes out of scope.
For anonymous fields this gets handled by the add_anonymous_field code that
removes the type from the declaration.
This patch does something similar in the parsing code when it is
detected we're dealing with an anonymous enum in a top-level declaration.
Closes GH-14839.
Older GCC versions (< 7.0) don't support the -Wno-implicit-fallthrough
compiler flag. This adds the flag conditionally in case some other
compiler will run into same issue.
Fixes GH-13330
We were using atoi, which is only for integers. When the size does not
fit in an integer this breaks. Use ZEND_STRTOUL instead. Also make sure
invalid data isn't accidentally parsed into a file size.
Closes GH-15035.
TIDY_APPLY_CONFIG can early return because it's a macro, but then the
cleanup paths are not executed. Transform this to a real function and
handle the cleanups correctly at the callsites.
Closes GH-15046.
RFC 2617 and 7616 describe that for the "Authorization" header we should
not put the qop nor nc value inside quotes. This differs from the
WWW-Authenticate header, which may have been the source of the confusion
in the implementation. While the version with quotes seems to work fine
in some cases, clearly not all servers accept the non-standard form.
To fix the issue, simply removing the quotes of those two header fields
of the client request to be in line with the RFC suffices.
I refer further to example 3.5 in RFC 2617 and example 3.9.1 in
RFC 7616.
RFC 2617: https://datatracker.ietf.org/doc/html/rfc2617

This was only partially fixed in PHP-8.3. Backports and fixes the case for both
initialized and uninitialized property writes.

According to the docs (https://www.php.net/manual/en/function.imagecreatefromwebp.php and https://www.php.net/manual/en/function.imagewebp.php), `false` should be returned on errors (similar to other functions of the `gd` extension), but actually all errors result in a `Fatal Error`. It doesn't look normal when trying to read an empty file or a file in the wrong format causes the program to stop. The problem seems to be related to a mega-patch that replaced `zend_error` with `zend_error_noreturn` almost everywhere. My patch fixes this behavior by switching from `zend_error_noerror` to `gd_error` (i.e. to `E_WARNING` level). All necessary memory cleanup is already in the code (as it was before the "zend_error_noreturn" patch).

The create_obj handler of InternalIterator is overwritten, but not the
clone_obj handler. This is not allowed.
In PHP 8.2 this didn't cause a segfault because the standard object
handler was used for the clone instead of the internal handler.
So then it allocates and frees the object using the standard object handlers.
In 8.3 however, the object is created using the standard object handler and
freed using the custom handler, resulting in the buffer overflow.
Even though bisect points to 1e1ea4f this only reveals the bug.
Closes GH-14882.
When dealing with a file, we must free the contents if the function
fails. While here, also fix the error message because previously it
sounded like the filename was too long while in fact the file itself
is too large.
Closes GH-14862.
`spl_object_storage_attach_handle` creates an entry already, but only
fills it in at the end with `spl_object_storage_create_element` which
allocates memory. In this case the allocation fails and we're left with
a NULL slot. Doing the allocation first isn't an option because we want
to check whether the slot is occupied before allocating memory.
The simplest solution is to set the entry to NULL and check for a NULL
pointer upon destruction.
Closes GH-14849.
libxml2 2.13 makes changes to how the parsing state is set, update our
code accordingly. In particular, it started reporting entities within
attributes, while it should only report entities inside text nodes.
Closes GH-14837.
This broke in 6318040df2 when phpdbg
stopped using its custom printing routines. By relying on standard
printing routines, the embedded NUL bytes are causing the strings to be
cut off, even when using %.*s. Solve this by going straight to the
output routine, which is what the printf routine would've done anyway.
Closes GH-14822.
You cannot return or yield a reference to a nullsafe chain. This was
checked already in zend_compile_return but not yet in
zend_compile_yield.
Closes GH-14716.
Remove xmlErrMemory from the export section for Windows, this fixes the
build. Even though the original function was renamed [1] it is hidden,
so removing this should be sufficient and not be a BC break.

Closes GH-14719.
The xinclude code from libxml removes the fallback node,
but the fallback node is still reference via $fallback.
The solution is to detach the nodes that are going to be removed in
advance.
Closes GH-14704.
Values retrieved from zend_getenv should be freed.
Note: The only possible value for `zend_getenv` is `sapi_getenv` which uses
zend alloc to duplicate the string that it reads from the SAPI module.
Closes GH-14708.
