Absolutely not. The baseline is that you have *no* permissions. This
is why a license is called just that: it is a license to do things
which are normally not permitted under copyright law.
As a consequence, if a piece of software is composed partly of code
released under license A, which grants you permissions X and Y, and
partly of code released under license B, which grants you permissions
Y and Z, the effect as regards the combined work is to grant you
*only* permission Y. License A's grant of permission X does not
extend to the code that is covered by license B; neither does license
B's grant of permission Y extend to the code that is covered by

Only the copyright owner or his / her agent can grant additional
licenses. Anyone redistributing the work (if the original license
allows such redistribution) can issue restrictions unless the original
license forbids it (as the GPL, but not the BSDL, does).
