This allows an attacker to use one AK, EK pair from a real TPM to pass EK validation and give the verifier an AK of a software TPM. A successful attack breaks the entire chain of trust because a not validated AK is used by the verifier. This issue is worse if the validation happens first and then the agent gets added to the verifier because the timing is easier and the verifier does not validate the regcount entry being equal to 1, CVE-2022-1053 SUSE Linux Enterprise Module for Basesystem 15 SP4:keylime-agent-6.3.2-150400.4.11.1 SUSE Linux Enterprise Module for Basesystem 15 SP4:keylime-config-6.3.2-150400.4.11.1 SUSE Linux Enterprise Module for Basesystem 15 SP4:keylime-firewalld-6.3.2-150400.4.11.1 SUSE Linux Enterprise Module for Basesystem 15 SP4:keylime-logrotate-6.3.2-150400.4.11.1 SUSE Linux Enterprise Module for Basesystem 15 SP4:keylime-registrar-6.3.2-150400.4.11.1 SUSE Linux Enterprise Module for Basesystem 15 SP4:keylime-tpm_cert_store-6.3.2-150400.4.11.1 SUSE Linux Enterprise Module for Basesystem 15 SP4:keylime-verifier-6.3.2-150400.4.11.1 SUSE Linux Enterprise Module for Basesystem 15 SP4:python3-keylime-6.3.2-150400.4.11.1 openSUSE Leap 15.4:keylime-agent-6.3.2-150400.4.11.1 openSUSE Leap 15.4:keylime-config-6.3.2-150400.4.11.1 openSUSE Leap 15.4:keylime-firewalld-6.3.2-150400.4.11.1 openSUSE Leap 15.4:keylime-registrar-6.3.2-150400.4.11.1 openSUSE Leap 15.4:keylime-tpm_cert_store-6.3.2-150400.4.11.1 openSUSE Leap 15.4:keylime-verifier-6.3.2-150400.4.11.1 openSUSE Leap 15.4:python3-keylime-6.3.2-150400.4.11.1 important To install this SUSE Security Update use the SUSE recommended installation methods like YaST online_update or "zypper patch". https://www.suse.com/support/update/announcement/2022/suse-su-20222658-1/ https://www.suse.com/security/cve/CVE-2022-1053.html CVE-2022-1053 https://bugzilla.suse.com/1199253 SUSE Bug 1199253 A UNIX Symbolic Link (Symlink) Following vulnerability in keylime of openSUSE Tumbleweed allows local attackers to escalate from the keylime user to root.
