For more details about the security issue(s), including the impact, a CVSS 
score, acknowledgments, and other related information, refer to the CVE page(s) 
listed in the References section.

Bug Fix(es):

* The RSAPSSSignature implementation works with RSA keys via the SunRSASign 
provider. However, it did not fully check that the RSA key could be used by the 
provider before attempting to do so, leading to the possibility of errors being 
returned with custom security providers. The implementation now validates RSA 
keys and will allow other providers to handle such keys where it cannot.
