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

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",
