Login problem after yum update

[P J P]

   Hi,

After I did yum update today morning(May 10'Th), I'm facing a weird login problem. None of the authentications - gdm login, su - user, or ssh from a remote host etc. are being resolved.

Even passwd(1) segfaluts while changing password.

I just can't login to the machine, in any way.

did anyone had the same experience? Below is the yum history of the last update transaction.

Thanks.
