CVE-2026-58471: Iconv E2big Outlen Overflow
The output buffer remaining length (`outlen`) is incorrectly set to the total allocated size after an E2BIG error during `iconv` character conversion. Because the output pointer is also advanced by the already used bytes (`done`), this allows `iconv` to write past the end of the allocated heap buffer on the next iteration.
