Description A Missing Release of Memory after Effective Lifetime issue in the Public Key Infrastructure daemon (pkid) of Juniper Networks Junos OS allows an unauthenticated networked attacker to cause Denial of Service (DoS). This occurs when Public Key Infrastructure (PKI) is used in combination with Certificate Revocation List (CRL), and the CRL fails to download, causing the memory allocated to store the CRL to not be released. Repeated occurrences will eventually consume all available memory, leading to an inoperable state of the affected system, causing a DoS.
