The PKI functionality in Cisco IOS 15.0 and 15.1 does not prevent permanent caching of certain public keys, which allows remote attackers to bypass authentication and have unspecified other impact by leveraging an IKE peer relationship in which a key was previously valid but later revoked, aka Bug ID CSCth82164, a different vulnerability than CVE-2010-4685.
