Description:
Two vulnerabilities were reported in RSA BSAFE Crypto-J. A remote user can bypass security controls on the target system. A remote user can obtain potentially sensitive information on the target system.
The software does not restrict OCSP response validity times when the optional nextUpdate value is not provided [CVE-2016-8212]. As a result, an OCSP response may be considered valid indefinitely.
A remote user can conduct a timing attack by modifying and submitting a PKCS#12 file and monitoring the resulting processing time to determine the valid MAC [CVE-2016-8217].
|
Impact:
A remote user can bypass OCSP time validity restrictions on the target system.
A remote user can determine the valid MAC for PKCS#12 files on the target system.
|
Solution:
The vendor has issued a fix (6.2.2; Advisory ESA-2016-154).
