TDengine is a time-series database optimized for Internet of Things devices. Prior to 3.4.1.14, source/libs/parser/src/parTokenizer.c tGetToken() incremented past a trailing backslash in a SQL string literal such as 'abc\ and read one byte beyond the null terminator, allowing an authenticated user who can submit SQL queries to crash the server and possibly leak adjacent memory. This issue is fixed in version 3.4.1.14.
