  - CVE-2025-29087: The concat_ws() SQL function can cause memory to be written
  beyond the end of a malloc-allocated buffer. If the separator argument is attacker-controlled and
  has a large string (e.g., 2MB or more), an integer overflow occurs in calculating the size of the
  result buffer, and thus malloc may not allocate enough memory.

  - CVE-2025-3277: An integer overflow can be triggered in SQLite `concat_ws()`function.
  The resulting, truncated integer is then used to allocate a buffer. When SQLite then
  writes the resulting string to the buffer, it uses the original, untruncated size and thus a
  wild Heap Buffer overflow of size ~4GB can be triggered. This can result in arbitrary
  code execution.");
