TODO
^^^^
:cve:`2025-48379`: Write buffer overflow on BCn encoding
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
TODO
There is a heap buffer overflow when writing a sufficiently large (>64k encoded with
default settings) image in the DDS format due to writing into a buffer without checking
for available space.
:cve:`YYYY-XXXXX`: TODO
^^^^^^^^^^^^^^^^^^^^^^^
This only affects users who save untrusted data as a compressed DDS image.
TODO
* Unclear how large the potential write could be. It is likely limited by process
segfault, so it's not necessarily deterministic. It may be practically unbounded.
* Unclear if there's a restriction on the bytes that could be emitted. It's likely that
the only restriction is that the bytes would be emitted in chunks of 8 or 16.
