Description Philipp Hahn univentionstaff 2019-12-18 09:49:58 CET
New Debian intel-microcode 3.20191115.2~deb9u1 fixes:
This update addresses the following issues:
* This update ships updated CPU microcode for some types of Intel CPUs. In particular it provides mitigations for the TAA (TSX Asynchronous Abort) vulnerability. For affected CPUs, to fully mitigate the vulnerability it is also necessary to update the Linux kernel. (CVE-2019-11135, CVE-2019-11139)
