SynopsisThe remote Debian host is missing a security update.
DescriptionIt 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 etc. This fix adds amd-microcode-based IBPB support.
For Debian 8 'Jessie', this problem has been fixed in version 3.20181128.1~deb8u1.
We recommend that you upgrade your amd64-microcode package.
NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
SolutionUpgrade the affected amd64-microcode package.
