3APA3A reports : If programmer fails to check socket number before using select() or fd_set macros, it's possible to overwrite memory behind fd_set structure. Very few select() based application actually check FD_SETSIZE value. [...] Depending on vulnerable application it's possible to overwrite portions of memory. Impact is close to off-by-one overflows, code execution doesn't seems exploitable.
