Out-of-bounds Read

Overview Affected versions of this package are vulnerable to Out-of-bounds Read in kekunwrapkey in the CMS component. An attacker supplying malicious CMS data can select a stream-mode KEK cipher via the OID in the PWRI keyEncryptionAlgorithm, defeating the block-length minimum-length guard so tha...
