IBM has released a patch for Lotus Domino to plug a security flaw which was disclosed in the latest Shadow Broker revelations. Lotus Domino includes an IMAP server. IMAP or Internet Message Access Protocol is an Internet standard protocol used by e-mail clients to retrieve e-mail messages from the mail server over a TCP/IP connection. The server contains a stack buffer overflow in the handling of mailbox names. This vulnerability affects Domino server 9.0.1FP8 and earlier versions, and this exploit has been referred to by the “EMPHASISMINE” code name by Shadow Brokers. CVE-2017-1274 has been assigned to this issue.
