CVE-ID: CVE-2020-24612
BDU-ID: None
CVE-Crit: MEDIUM
CVE-DESC.: A problem was detected in the selinux-policy package because the .config/Yubico directory is not handled correctly. Consequently, when SELinux is in forced mode, pam-u2f cannot read the user’s U2F configuration file. If configured with the nouserok option (the default when configured with the authselect tool) and this file cannot be read, the second factor is disabled. An attacker who only knows the password can log in by bypassing 2FA.
CVE-STATUS: Not relevant
