Libsunec Project: >> Libsunec Security Vulnerabilities
The Elliptic Curve Cryptography library (aka sunec or libsunec) allows a memory-cache side-channel attack on ECDSA signatures, 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.
