Embedded ComponentCVE IDSummary of VulnerabilityReason why Product is not VulnerableDate Determined False Positive
Crypto-JCVE-2018-0495Libgcrypt before 1.7.10 and 1.8.x before 1.8.3 allows a memory-cache side-channel attack on ECDSA signatures that can be mitigated through the use of blinding during the signing process in the _gcry_ecc_ecdsa_sign function in cipher/ecc-ecdsa.c, aka the Return Of the Hidden Number Problem or ROHNP. To discover an ECDSA key, the attacker needs access to either the local machine or a different virtual machine on the same physical host.ROHNP is a timing attack when computing the s value of a signature for DSA and ECDSA: s = (m + r * x) / k.  Flush+Reload is one technique that works for this attack and it has been determined that the JDK/JRE currently supported by Crypto-J is not vulnerable to the Flush+Reload attack, at least given current JDK behavior and 64-bit x86-64 processor.11/19/2018
