| 제목 | dvidelabs flatcc v0.6.3 Reachable Assertion |
|---|
| 설명 | FlatBuffers structs must be acyclic (a struct's fields may only reference other structs by value if the graph is a DAG), but the parser does not reject mutually-recursive structs up front. analyze_struct() re-enters struct analysis while the fb_circular_open flag for the enclosing struct is still set (src/compiler/semantics.c:695), and the cycle trips an assertion that aborts the compile with SIGABRT.
Affected versions: flatcc v0.6.3
Severity: Medium (reachable assertion abort / SIGABRT; crash/DoS of the schema compiler)
CWE: CWE-617 (Reachable Assertion) |
