bug-of-the-month club

n. [from book-of-the-month club , a time-honored mail-order-marketing
technique in the U.S.] A mythical club which users of sendmail (8) (the Unix
mail daemon) belong to; this was coined on the Usenet newsgroup
comp.security.unix at a time when sendmail security holes, which allowed
outside cracker s access to the system, were being uncovered at an alarming
rate, forcing sysadmins to update very often. Also, more completely, fatal
security bug-of-the-month club. See also kernel-of-the-week club.
