Hi, another imap crash with latest dovecot.
segmentation fault in fetch_bodystructure
src/imap/imap-fetch.c static int fetch_bodystructure(struct imap_fetch_context *ctx, struct mail *mail, void *context ATTR_UNUSED) { const char *bodystructure;
if (mail_get_special(mail, MAIL_FETCH_IMAP_BODYSTRUCTURE,
&bodystructure) < 0)
return -1;---> before the segfault here we have bodystructure=0 and mail_get_special returns >=0 [..]
if (o_stream_send(ctx->client->output, "BODYSTRUCTURE (", 15) < 0 ||/*line 461*/ o_stream_send_str(ctx->client->output, bodystructure) < 0 ||
---> here o_stream_send_str calls strlen(bodystructure=0), and strlen tries to access "Address 0x0" causing a segfault
