linux - security update


Multiple researchers have discovered vulnerabilities in the way the Intel processor designs have implemented speculative forwarding of data filled into temporary microarchitectural structures (buffers). This flaw could allow an attacker controlling an unprivileged process to read sensitive information, including from the kernel and all other processes running on the system or cross guest/host boundaries to read host memory. See [\ https://www.kernel.org/doc/html/latest/admin-guide/hw-vuln/mds.html](https://www.kernel.org/doc/html/latest/admin-guide/hw-vuln/mds.html) for more details. To fully resolve these vulnerabilities it is also necessary to install updated CPU microcode. An updated intel-microcode package (only available in Debian non-free) will be provided via a separate DSA. The updated CPU microcode may also be available as part of a system firmware ("BIOS") update. In addition, this update includes a fix for a regression causing deadlocks inside the loopback driver, which was introduced by the update to 4.9.168 in the last Stretch point release. For the stable distribution (stretch), these problems have been fixed in version 4.9.168-1+deb9u2. We recommend that you upgrade your linux packages.
