Description
MailEnable Enterprise Premium before 10.62 contains a heap overflow vulnerability in the IMAP X-FB-FETCH command that allows authenticated users to overflow a fixed 0x400-byte heap buffer. Attackers can supply an X-FB-USER address longer than about 1016 bytes, which is formatted without a length check, to crash the IMAP service and cause denial of service.
