USN-8672-1: SSSD vulnerability
It was discovered that the SSSD PAM responder may crash if a physically proximate attacker manipulates a smartcard or Yubikey. Non-malicious physically proximate users may not be able to log in depending upon the details of their legitimate smartcard or Yubikey...
The vulnerability of the `pam_passkey_child_read_data()` function in the `src/responder/pam/pamsrv_passkey.c` file of the access control service for remote directories and the SSSD authentication mechanism allows a hacker to cause a service failure.
The vulnerability of the pampasskeychildreaddata function in the src/responder/pam/pamsrvpasskey.c file of the access control service for remote directories and the SSSD authentication mechanism is related to a buffer overflow. Exploiting this vulnerability could allow an attacker to cause a...
