Dear Team,
File: localauth_k5login.c#L110
I believe this indicates a security flaw, If an attacker can change
anything along the path between the call access() and the files actually
used, attacker may exploit the race condition or a time-of-check,
time-of-use race condition, request team to please have a look and
validate.
Thank you
