-- RHSA-announce mailing list RHSA-announce@redhat.com https://listman.redhat.com/mailman/listinfo/rhsa-announce . ========================================================================= Ubuntu Security Notice USN-4985-1 June 09, 2021

intel-microcode vulnerabilities

A security issue affects these releases of Ubuntu and its derivatives:

  • Ubuntu 21.04
  • Ubuntu 20.10
  • Ubuntu 20.04 LTS
  • Ubuntu 18.04 LTS
  • Ubuntu 16.04 ESM
  • Ubuntu 14.04 ESM

Summary:

Several security issues were fixed in Intel Microcode. This may allow a local user to perform a privilege escalation attack. (CVE-2021-24489)

Joseph Nuzman discovered that some Intel processors may not properly apply EIBRS mitigations (originally developed for CVE-2017-5715) and hence may allow unauthorized memory reads via sidechannel attacks. A local attacker could use this to expose sensitive information, including kernel memory. (CVE-2020-24511)

Travis Downs discovered that some Intel processors did not properly flush cache-lines for trivial-data values. This may allow an unauthorized user to infer the presence of these trivial-data-cache-lines via timing sidechannel attacks. A local attacker could use this to expose sensitive information. (CVE-2020-24512)

It was discovered that certain Intel Atom processors could expose memory contents stored in microarchitectural buffers. A local attacker could use this to expose sensitive information. (CVE-2020-24513)

Update instructions:

The problem can be corrected by updating your system to the following package versions:

Ubuntu 21.04: intel-microcode 3.20210608.0ubuntu0.21.04.1

Ubuntu 20.10: intel-microcode 3.20210608.0ubuntu0.20.10.1

Ubuntu 20.04 LTS: intel-microcode 3.20210608.0ubuntu0.20.04.1

Ubuntu 18.04 LTS: intel-microcode 3.20210608.0ubuntu0.18.04.1

Ubuntu 16.04 ESM: intel-microcode 3.20210608.0ubuntu0.16.04.1+esm1

Ubuntu 14.04 ESM: intel-microcode 3.20210608.0ubuntu0.14.04.1+esm1

After a standard system update you need to reboot your computer to make all the necessary changes.

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and some for Skylake R0/D0 CPUs on systems using a very outdated firmware/BIOS, the system may hang on boot: (https://github.com/intel/Intel-Linux-Processor-Microcode-Data-Files/issues/31)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/

This may allow a local user to perform a privilege escalation\nattack. (CVE-2021-24489)\n\nJoseph Nuzman discovered that some Intel processors may not properly apply\nEIBRS mitigations (originally developed for CVE-2017-5715) and hence may\nallow unauthorized memory reads via sidechannel attacks. A local attacker\ncould use this to expose sensitive information, including kernel\nmemory. (CVE-2020-24511)\n\nTravis Downs discovered that some Intel processors did not properly flush\ncache-lines for trivial-data values. This may allow an unauthorized user to\ninfer the presence of these trivial-data-cache-lines via timing sidechannel\nattacks. A local attacker could use this to expose sensitive\ninformation. (CVE-2020-24512)\n\nIt was discovered that certain Intel Atom processors could expose memory\ncontents stored in microarchitectural buffers. A local attacker could use\nthis to expose sensitive information. (CVE-2020-24513)\n\nUpdate instructions:\n\nThe problem can be corrected by updating your system to the following\npackage versions:\n\nUbuntu 21.04:\n  intel-microcode                 3.20210608.0ubuntu0.21.04.1\n\nUbuntu 20.10:\n  intel-microcode                 3.20210608.0ubuntu0.20.10.1\n\nUbuntu 20.04 LTS:\n  intel-microcode                 3.20210608.0ubuntu0.20.04.1\n\nUbuntu 18.04 LTS:\n  intel-microcode                 3.20210608.0ubuntu0.18.04.1\n\nUbuntu 16.04 ESM:\n  intel-microcode                 3.20210608.0ubuntu0.16.04.1+esm1\n\nUbuntu 14.04 ESM:\n  intel-microcode                 3.20210608.0ubuntu0.14.04.1+esm1\n\nAfter a standard system update you need to reboot your computer to make\nall the necessary changes. \n\nFor the stable distribution (buster), these problems have been fixed in\nversion 3.20210608.2~deb10u1. \n\nNote that there are two reported regressions; for some CoffeeLake CPUs\nthis update may break iwlwifi\n(https://github.com/intel/Intel-Linux-Processor-Microcode-Data-Files/issues/56)\nand some for Skylake R0/D0 CPUs on systems using a very outdated firmware/BIOS,\nthe system may hang on boot:\n(https://github.com/intel/Intel-Linux-Processor-Microcode-Data-Files/issues/31)\n\nIf you are affected by those issues, you can recover by disabling microcode\nloading on boot (as documented in README.Debian (also available online at\nhttps://salsa.debian.org/hmh/intel-microcode/-/blob/master/debian/README.Debian))\n\nWe recommend that you upgrade your intel-microcode packages. \n\nFor the detailed security status of intel-microcode please refer to\nits security tracker page at:\nhttps://security-tracker.debian.org/tracker/intel-microcode\n\nFurther information about Debian Security Advisories, how to apply\nthese updates to your system and frequently asked questions can be\nfound at: https://www.debian.org/security/\n\nMailing list: debian-security-announce@lists.debian.org\n-----BEGIN PGP SIGNATURE-----\n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\n9lmsnX3+5GWM7Fx2NN2vL5xIEo0einMJCyTlNMRDLim2ix1vpZg=\n=RVf2\n-----END PGP SIGNATURE-----\n",
