Description
An out-of-bounds read vulnerability exists in the schema lexer of flatcc 4c3b999e. When an exact-length FlatBuffers schema ends with an unterminated quotation mark, the C-string scanning logic in lex() dereferences the input pointer after it has reached the end of the buffer. A specially crafted schema can trigger a one-byte heap buffer over-read, resulting in application crash and denial of service.
