If the debug option is enabled in the PAM configuration, part of the file contents of a symlink target will be logged, possibly revealing sensitive information.

This leads to the file descriptor being inherited into the child process; the child process can then read from and write to it. This can leak sensitive information and also, if written to, be used to fill the disk or plant misinformation. CVE-2019-12210 openSUSE Tumbleweed:pam_u2f-1.1.1-1.3 moderate 5.5 AV:N/AC:L/Au:S/C:P/I:P/A:N To install this SUSE Security Update use the SUSE recommended installation methods like YaST online_update or "zypper patch". https://www.suse.com/security/cve/CVE-2019-12210.html CVE-2019-12210 https://bugzilla.suse.com/1087061 SUSE Bug 1087061 https://bugzilla.suse.com/1135727 SUSE Bug 1135727 https://bugzilla.suse.com/1135729 SUSE Bug 1135729 Yubico pam-u2f before 1.1.1 has a logic issue that, depending on the pam-u2f configuration and the application used, could lead to a local PIN bypass. This issue does not allow user presence (touch) or cryptographic signature verification to be bypassed, so an attacker would still need to physically possess and interact with the YubiKey or another enrolled authenticator. If pam-u2f is configured to require PIN authentication, and the application using pam-u2f allows the user to submit NULL as the PIN, pam-u2f will attempt to perform a FIDO2 authentication without PIN. If this authentication is successful, the PIN requirement is bypassed.
