CVE-2018-3639

Systems with microprocessors utilizing speculative execution and speculative execution of memory reads before the addresses of all prior memory writes are known may allow unauthorized disclosure of information to an attacker with local user access via a side-channel analysis, aka Speculative Stor...

CVE-2018-3639

CVE-2018-3639 is a speculative execution side‑channel vulnerability (SSB) that can leak memory via speculative stores. The Connected ALMA doc notes a mitigation: SSB is disabled by the new alt-java launcher, reducing impact at the cost of performance, and it references OpenJDK 8u282 as part of th...
