CVE-2025-3277

An integer overflow can be triggered in SQLite’s `concat_ws()` function.

MEDIUM 6.9EPSS 0.83%

Does this matter?

Lower severity and a low EPSS score (0.83%). Track it; it rarely justifies an emergency change on its own.

Description

An integer overflow can be triggered in SQLite’s `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.
