提出 #919199: dvidelabs flatcc v0.6.3 Memory Leak情報

タイトルdvidelabs flatcc v0.6.3 Memory Leak
説明define_fb_name() inserts reserved keywords into a dedicated keyword_index hash table (src/compiler/semantics.c:260). The parser's teardown (fb_clear_parser) frees the attribute_index and include_index tables but omits keyword_index, so every schema parse leaks the keyword table (~1024 bytes). For any persistent process (fuzz harness, daemon, IDE language server) that parses schemas repeatedly, memory grows without bound. Affected versions: flatcc HEAD v0.6.3 Severity: Medium (deterministic per-parse memory leak; DoS by resource exhaustion in persistent processes) CWE: CWE-401 (Improper Release of Memory Before Removing Last Reference)
