Use after free in PostgreSQL COPY FROM error reporting allows a database user to disclose portions of server memory, via a longer input row following an ignored or nullified conversion error. file_fdw reaches the same code path in affected version 18. Within major versions 17-18, minor versions before PostgreSQL 18.7 and 17.12 are affected. Versions before PostgreSQL 17 are unaffected.
Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).
