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
