Eric Biggers d39838a556 509: fix printing uninitialized stack memory when OID is empty
[ Upstream commit 8dfd2f22d3 ]

Callers of sprint_oid() do not check its return value before printing
the result.  In the case where the OID is zero-length, -EBADMSG was
being returned without anything being written to the buffer, resulting
in uninitialized stack memory being printed.  Fix this by writing
"(bad)" to the buffer in the cases where -EBADMSG is returned.

Fixes: 4f73175d03 ("X.509: Add utility functions to render OIDs as strings")
