Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Buffer overflow in the IMAP service of Mercury (Pegasus) Mail 4.01 allows remote attackers to execute arbitrary code via a long SELECT command.
