TITLE

Debian Security Advisory 4934-1

Trust: 0.1

sources: PACKETSTORM: 169079

DESCRIPTION

Observable timing discrepancy in some Intel(R) Processors may allow an authenticated user to potentially enable information disclosure via local access. For the stable distribution (buster), these problems have been fixed in version 3.20210608.2~deb10u1. Note that there are two reported regressions; for some CoffeeLake CPUs this update may break iwlwifi (https://github.com/intel/Intel-Linux-Processor-Microcode-Data-Files/issues/56) and some for Skylake R0/D0 CPUs on systems using a very outdated firmware/BIOS, the system may hang on boot: (https://github.com/intel/Intel-Linux-Processor-Microcode-Data-Files/issues/31) If you are affected by those issues, you can recover by disabling microcode loading on boot (as documented in README.Debian (also available online at https://salsa.debian.org/hmh/intel-microcode/-/blob/master/debian/README.Debian)) We recommend that you upgrade your intel-microcode packages. For the detailed security status of intel-microcode please refer to its security tracker page at: https://security-tracker.debian.org/tracker/intel-microcode Further information about Debian Security Advisories, how to apply these updates to your system and frequently asked questions can be found at: https://www.debian.org/security/ Mailing list: debian-security-announce@lists.debian.org -----BEGIN PGP SIGNATURE----- iQIzBAEBCgAdFiEEtuYvPRKsOElcDakFEMKTtsN8TjYFAmDXan0ACgkQEMKTtsN8 Tja9aQ//f1dHsEghQsedGnkMCIa2qLi12UFtb4yW7TYV6uwloqbYZMbymvoXYOAB haasn+yCaGUkXuAHxcGvZuN41EkRhdG4LfS5qoZxPMsw84ETjpV2Ohwhuqwf9P20 9pqV1QLjVPCMiCqvHatkzyRNPtRhIh0uCRx5HtIeOEyKTwhVnUJrrljUXCzMDviD 3As0n0yVUPDIcJdaVxp5mxyebf1NyIYMR+7wmzTBOhK6i+rEE4NkKGkcsYBIM1ch AdTQNHv78QZld6ixL8iCUe1NsSugZ2QjbVL1BLW45fJv3f0BIF5uo6LBzbiJlN/6 xWwOdFTfqW1ORyr0k6JQ+yKz3oSE+jfUStwf+zegWOjYes5gGaA/nATzzNwwFfCQ qDqMmnN26qMI3MswP50ESkNs2JTK3955cIJjnscp5DeFArDuCFKh9wcqSZ46/QCE GVRi+F/Dh3JQxv/jP8jfLhCvkBptuendGo9qK5v22QoeCRoHS16dLu7HHP34hRrw k//EgtP35pD9eTNiIsxhmx3qTPD0gbQbcMG/5NTVtpNqsffAxYtqTy8+/4lfPkNn AYtYrrG6tjEHe1gasLkjthB7c0YLzPLdNyZkNIk6XZ2YIhx18N80c7gTBERSJ1Sh 9lmsnX3+5GWM7Fx2NN2vL5xIEo0einMJCyTlNMRDLim2ix1vpZg= =RVf2 -----END PGP SIGNATURE----- . -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 ==================================================================== Red Hat Security Advisory Synopsis: Important: microcode_ctl security, bug fix and enhancement update Advisory ID: RHSA-2021:2301-01 Product: Red Hat Enterprise Linux Advisory URL: https://access.redhat.com/errata/RHSA-2021:2301 Issue date: 2021-06-08 CVE Names: CVE-2020-24489 CVE-2020-24511 CVE-2020-24512 CVE-2020-24513 ==================================================================== 1.
