** DISPUTED ** The standardise function in Anibal Monsalve Salazar sSMTP 2.61 and 2.62 allows local users to cause a denial of service (application exit) via an e-mail message containing a long line that begins with a . (dot) character. NOTE: CVE disputes this issue because it is solely a usability problem for senders of messages with certain long lines, and has no security impact.
