Description Laura Pardo 2018-06-15 18:30:43 UTC
BoringSSL through 2018-06-14 allows a memory-cache side-channel attack on DSA signatures, aka the Return Of the Hidden Number Problem or ROHNP. To discover a DSA key, the attacker needs access to either the local machine or a different virtual machine on the same physical host.
