Description
Aki Tuomi reports: Parsing mails with a large number of MIME parts could have resulted in excessive CPU usage or a crash due to running out of stack memory.. Dovecot's NTLM implementation does not correctly check message buffer size, which leads to reading past allocation which can lead to crash lmtp/submission: Issuing the RCPT command with an address that has the empty quoted string as local-part causes the lmtp service to crash. Dovecot's RPA mechanism implementation accepts zero-length message, which leads to assert-crash later on.
