CVE-2025-3277: Buffer Overflow
An integer overflow can be triggered in SQLite’s concatws() 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.
