It was discovered that systems with microprocessors utilizing
speculative execution and indirect branch prediction may allow
unauthorized disclosure of information to an attacker with local
user access via a side-channel analysis (Spectre v2).
Multiple fixes were done already in Linux kernel, intel-microcode,
et al. This fix adds amd-microcode-based IBPB support.
For Debian 9 stretch, this problem has been fixed in version
3.20181128.1~deb9u1.
We recommend that you upgrade your amd64-microcode packages.
