CVE-2016-8217 Information

Description

EMC RSA BSAFE Crypto-J versions prior to 6.2.2 has a PKCS12 Timing Attack Vulnerability. A possible timing attack could be carried out by modifying a PKCS12 file that has an integrity MAC for which the password is not known. An attacker could then feed the modified PKCS12 file to the toolkit and guess the current MAC one byte at a time. This is possible because Crypto-J uses a non-constant-time method to compare the stored MAC with the calculated MAC. This vulnerability is similar to the issue described in CVE-2015-2601.
