Package : intel-microcode
Version : 3.20180703.2~deb8u1
CVE ID : CVE-2018-3639 CVE-2018-3640
Security researchers identified two software analysis methods that, if
used for malicious purposes, have the potential to improperly gather
sensitive data from multiple types of computing devices with different
vendors processors and operating systems.
This update requires an update to the intel-microcode package, which
is non-free. Users who have already installed the version from
jessie-backports-sloppy do not need to upgrade.
CVE-2018-3639 - Speculative Store Bypass (SSB) - also known as Variant 4
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.
CVE-2018-3640 - Rogue System Register Read (RSRE) - also known as
Variant 3a
Systems with microprocessors utilizing speculative execution and
that perform speculative reads of system registers may allow
unauthorized disclosure of system parameters to an attacker with
local user access via a side-channel analysis.
For Debian 8 "Jessie", these problems have been fixed in version
3.20180703.2~deb8u1.
We recommend that you upgrade your intel-microcode packages.
