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.\n\n## Affected\n\n- `sqlite >= 3.44.0, < 3.49.1`\n\n## Remediation\n\nUpgrade past the affected range:\n\n- `sqlite 3.49.1`","depth":"midnight","depthScore":54,"depthScoreParts":{"impact":53.9,"likelihood":0.2,"exploitation":0,"ransomware":0},"changes":[]}
