-Subject: [PATCH] slirp: use correct size while emulating IRC commands
-
-While emulating IRC DCC commands, tcp_emu() uses 'mbuf' size
-'m->m_size' to write DCC commands via snprintf(3). This may
-lead to OOB write access, because 'bptr' points somewhere in
-the middle of 'mbuf' buffer, not at the start. Use M_FREEROOM(m)
-size to avoid OOB access.
