In enqueue_otr_fragment(), after a ?OTR: reassembly has been opened (opc->full_msg != NULL), the end-tag check evaluates msg[msg_len - 1] where msg_len is size_t. If a PRIVMSG whose body decodes to an empty string reaches this path, msg_len is 0 and msg_len - 1 wraps to SIZE_MAX, indexing far off the page and crashing irssi (SIGSEGV). The initial-fragment path is safe because it is gated by 'pos &&' (strstr of an empty string returns NULL), but the open-reassembly path has no such guard. recode_in() returns a non-NULL empty string for an empty PRIVMSG body, and sig_message_private (signal_add_first on "message private") feeds it straight to otr_receive()/enqueue_otr_fragment(). Relays/bouncers such as bitlbee/znc and some ircds pass PRIVMSGs with an empty trailing parameter through to the client. Drop an empty fragment early: if a reassembly is open, keep waiting for more (OTR_MSG_WAIT_MORE); otherwise treat it as an original message (OTR_MSG_ORIGINAL), matching the existing behaviour of the else branch. |
