  Although the possible existence of dangerous charge and color breaking (CCB)
directions in the MSSM has been known since the early 80's, only particular
directions in the field-space have been considered, thus obtaining necessary
but not sufficient conditions to avoid dangerous CCB minima. Furthermore, the
radiative corrections to the potential were not normally included in a proper
way, often leading to an overestimation of the restrictive power of the bounds.
It turns out that when correctly evaluated, the ``traditional" CCB bounds are
very weak. I give here a brief survey of recent results on this subject, which
represent a complete analysis, showing that the new CCB bounds are very strong
and, in fact, there are extensive regions in the parameter space that become
forbidden. This produces important bounds, not only on the value of $A$, but
also on the values of $B$ and $M_{1/2}$. The form of strongest one of the new
bounds, the so called UFB-3 bound, is explicitely given.
