* Also fix a potential buffer overflow when displaying the detailed HDD vs UFD score due to the
safe_sprintf() macro re-evaluating the expression passed as parameter.
* Also refactor and clean up the the safe_###() macros to avoid similar issues.
* Also use FOF_NO_UI as flag for SHDeleteDirectoryExU(), which may alleviate some Alt-D errors.
* As opposed to the ERROR_HANDLE_EOF we get when reading sectors from the VHD file directly, now that we mount
VHD/VHDX for reading, and access them as regular disks, we also need to process ERROR_SECTOR_NOT_FOUND as an
indicator for the end of the drive.
* Also switch to using GetOverlappedResultEx() with a timeout since we no longer have to cater for Windows 7.
* Closes#2468.
* Ubuntu changed their GRUB config format yet again, so our search for the kernel
config no longer works, and the 'persistent' option doesn't get added.
* Switch to a more generic '/casper/vmlinuz' search, though it might have unintended
consequences...
* Also fix a possible double free in FormatExtFs().
* is_in_md5sum() could partially match a string against another one, which, aside from matching
unwanted files, could also lead to files not being identified as being in the md5sum.txt if
the previous partial match happened to be with the current search target.
* Fix this by making sure that we always match a whole path followed by '/n', '/r' or '/0'.
* Not all md5sum.txt (e.g. Ubuntu 24.04) will reference the UEFI bootloader,
so we can't rely on using that data for the bootloader extraction.
* Instead, formally test for the presence of the bootloader on disk.
* The call returned the size occupied in blocks rather than the actual file size,
leading to issues such as Rufus not being able to identify the GRUB version used
by Ubuntu 24.04.
* The static_/safe_ string macros were not properly designed to handle the case where
an expression such as strlen() rather than a static value was passed for the count,
leading to unexpected results, such as excessive truncation of strings. Fix that.
* Also fix a buffer overflow in GetDevices() due to using a wrong string length.
* _snprintf() is not always guaranteed to NUL terminate a string which could
lead to buffer overflows in iso_extract_files() and iso_extract_files().
* Fix this by switching to using the more secure _snprintf_s().
* Vulnerability discovered and reported by Mansour Gashasbi (@gashasbi).
* For good measure, we also switch to the strncat_s() where possible and also
use memmove() instead of memcpy()/strcpy() as the behaviour of the latter on
overlapping memory regions is undefined.
* Also fix some additional MinGW warnings regarding casts and nb_blocks.
* p[safe_strlen(p)] = 0; was pointless and could lead to a buffer overflow if
the string was not already NUL terminated, so remove it and make sure we
process a buffer that either contains legitimate Syslinux version strings
(that are NUL terminated always) or that has been read through read_file()
(that always adds a NUL terminator to the buffer).
* Also fix some whitespaces in related code sections and switch to using
read_file() for GRUB version lookup.
* Vulnerability discovered and reported by Mansour Gashasbi (@gashasbi).
* Whereas the length of the buffer allocated for the UTF-8 filename string is
the same length as the UCS-2 (which means it can store twice as many UTF-8
bytes as there are characters in the filename), it is still possible for the
converted UTF-8 string to overflow this buffer if the name contains glyphs
that use 3 or 4-byte sequences.
* As a result, use strncpy with the actual size of the UTF-8 filename buffer
(the following bytes are calloc'd to zero so the truncated string will be
NUL terminated) and produce a warning if the filename is truncated.
* Vulnerability discovered and reported by Mansour Gashasbi (@gashasbi).
* Also add Ctrl-A as a new cheat-mode to toggle the use of Rufus MBR (which is enabled by default)
which replaces the previous UI checkbox. The Disk ID field is now completely removed as we now
use the default values for XP and non XP installs, and will expect people with multiple disks to
disconnect all except the one where they plan to install Windows.
* This allows *runtime* validation of UEFI bootable media, such as Windows
or Linux installers, which, considering the unreliability of USB flash
drives, we assert is a a much better proposal than write-time validation
that utilities like balenaEcther (and to a lesser extent MCT) provide.
* Based on uefi-md5sum (https://github.com/pbatard/uefi-md5sum).
* Unconditionally activated on ISO extraction for GPT targets for now.
This will be changed to a user selectable option later.
* This enables the use of Ctrl-SELECT to also extract files from a .zip
when using non-bootable, DOS, UEFI-NTFS, etc.
* Also clean up some uprintf line terminations and some additional code.
* Also fix some Coverity and MinGW warnings.
* The AMI UEFI NTFS driver (version 0x10000), which is used in many modern systems from
ASUS, Gigabyte, intel and so on, has a major bug whereas depending on the size of the
buffers that are used to write the data onto the NTFS volume from Windows, as well as
read the data from the NTFS volume from UEFI, the data being read may be incorrect
(for details on this, see https://github.com/pbatard/AmiNtfsBug).
* Especially, it appears that if the size of the buffer used to write data on Windows is
smaller than the NTFS cluster size, the bug may be triggered.
* Because of this, we increase the size of ISO write buffer to 64 KB since, per
https://support.microsoft.com/en-gb/topic/default-cluster-size-for-ntfs-fat-and-exfat-9772e6f1-e31a-00d7-e18f-73169155af95
this is the maximum cluster size that can be used for NTFS volumes.
* This increase in size should also help with performance somewhat.
* Also add support for C11's _Static_assert() which may come handy.
* The legacy code we used for writing disk images used the size of the source image as
the maximum number of bytes we should copy, which is fine for uncompressed DD or VHD
images, but not so much for compressed VHDX ones. So we now make sure to use the
actual size of the virtual disk, which we obtain when mounting the VHD/VHDX.
* Also fix log progress update as well as a MinGW warning.
* Mint users sure are lucky that one of them *lied their way through* pretending that
persistence actually used to work with previous version of Mint, when it never did,
because they got us going through a whole refactor of the partition creation process
just so we could make Mint persistence work.
* Closes#2428.
* Also fix a Coverity warning.
