Details

OpenSMTPD before 6.6.4 allows remote code execution because of an out-of-bounds read in mtaio in mtasession.c for multi-line replies. Although this vulnerability affects the client side of OpenSMTPD, it is possible to attack a server because the server code launches the client code during bounce handling.
