Dear,
use our static analysis tools, I find some bugs (Null deference pointer) for dovecot-2.2.18. Null deference pointer bugs often make program crashes, Please confim them, Thanks! 1. dovecot-2.2.18/src/config/config-request.c 332 'setting_export_section_name(ctx->prefix, def, children[i], i);', pointer 'children' in line 202 assigned NULL and if branch 'case SET_DEFLIST_UNIQUE' not execute, so pointer 'children' is always NULL. It load to a bug of null deference pointer In line 332. The same bugs also appeared in : 1. dovecot-2.2.18/src/lib-index/mail-index-fsck.c line 170 or 174, pointer 'kw_rec ' mybe NULL. 2.dovecot-2.2.18/src/lib-storage/mail-search-args-simplify line 349, pointer 'prev_arg' mybe NULL. best wishes~ Amy
