Subject: [PATCH 1/3] plug-ins: Fix DDS vulnerability (ZDI-CAN-22093)
Resolves #10069
Currently, the DDS header information for the width, height, and bytes per scan line
are read in and assumed to be correct. As these values are used for memory allocation
and reading, it would be good to verify they do not exceed the file size.
This patch adds a condition after the header is read in to verify those values. If they exceed
the file size (mins an offset), the file is not read in and an error message is shown.

Subject: [PATCH 2/3] plug-ins: Fix DDS import regression from 7db71cd0
@Wormnest pointed out that compressed files are likely smaller than
width * height * bps, so our check to prevent ZDI-CAN-22093
also caught valid files.
The size check is removed from load_image () and moved to load_layer ()
before the two fread() functions, as we know exactly how much we'll
try to read at that point.

Subject: [PATCH 3/3] plug-ins: Additional fixes for DDS Import
@Wormnest noted remaining regressions after 8faad92e.
The second fread() only runs if the DDSD_PITCH flag is set,
so the error handling check should also be conditional.
Additionally, the ZDI-CAN-22093 exploit no longer runs but
still could cause a plug-in crash. This patch adds an additional
check to ensure the buffer size was within bounds.

Subject: [PATCH] plug-ins: Fix PSP vulnerability (ZDI-CAN-22096)
Resolves #10072.
The current PSP palette loading code does not check if
the file's palette entry count value is below the limit
(G_MAXUNIT32 / 4 due to each color being 4 bytes long).
This patch adds this check and stops loading if the count
is larger than GIMP currently supports.

Subject: [PATCH] plug-ins: Fix PSP vulnerability (ZDI-CAN-22097)
Resolves #10071.
When reading RLE compressed data, a buffer was allocated to 127 bytes.
However, it can potentially be used to read 128 bytes, leading to a
off-by-one vulnerability. This patch allocates 128 bytes to the buffer
to prevent this from occurring.
