Description Pedro Sampaio 2022-11-22 18:11:25 UTC 
A segmentation fault due to a null pointer dereference has been found in the IMAP STATUS command handling component. The error occurs when mailimap_mailbox_data_status_free in low-level/imap/mailimap_types.c when it tries to free st_info_list of mb_data_status. The segmentation fault is triggered when an invalid STATUS response is received. This can at least lead to a Denial Of Service.
