openjdk-jre is a free and open-source implementation of the Java Platform, Standard Edition (Java SE).
Affected versions of this package are vulnerable to Timing Attack. Timing attacks are possible in implementations of
ECDSA/EdDSA in cryptographic software libraries which allows for practical recovery of the long-term private key. This is possible in implementations which leak the bit-length of the scalar during scalar multiplication on an elliptic curve. This leakage might seem minuscule as the bit-length presents a very small amount of information present in the scalar. However, in the case of ECDSA/EdDSA signature generation, the leaked bit-length of the random nonce is enough for full recovery of the private key used after observing a few hundreds to a few thousands of signatures on known messages, due to the application of lattice techniques.
openjdk-jre to version 8.0.232, 11.0.5 or higher.
