Multiple Cisco products are affected by a vulnerability involving the Open Shortest Path First (OSPF) Routing Protocol Link State Advertisement (LSA) database. This vulnerability could allow an unauthenticated attacker to take full control of the OSPF Autonomous System (AS) domain routing table, blackhole traffic, and intercept traffic.

The attacker could trigger this vulnerability by injecting crafted OSPF packets. Successful exploitation could cause flushing of the routing table on a targeted router, as well as propagation of the crafted OSPF LSA type 1 update throughout the OSPF AS domain.

To exploit this vulnerability, an attacker must accurately determine certain parameters within the LSA database on the target router. This vulnerability can only be triggered by sending crafted unicast or multicast LSA type 1 packets. No other LSA type packets can trigger this vulnerability.

OSPFv3 is not affected by this vulnerability. Fabric Shortest Path First (FSPF) protocol is not affected by this vulnerability.

Multiple Cisco products incorporate a version of the OpenSSL package affected by a vulnerability that could allow an unauthenticated, remote attacker to retrieve memory in chunks of 64 kilobytes from a connected client or server.

The vulnerability is due to a missing bounds check in the handling of the Transport Layer Security (TLS) heartbeat extension. An attacker could exploit this vulnerability by implementing a malicious TLS or Datagram Transport Layer Security (DTLS) client, if trying to exploit the vulnerability on an affected server, or a malicious TLS or DTLS server, if trying to exploit the vulnerability on an affected client. An exploit could send a specially crafted TLS or DTLS heartbeat packet to the connected client or server. An exploit could allow the attacker to disclose a limited portion of memory from a connected client or server for every heartbeat packet sent. The disclosed portions of memory could contain sensitive information that may include private keys and passwords.

Please note that the devices that are affected by this vulnerability are the devices acting as an SSL server terminating SSL connections or devices acting as an SSL Client initiating an SSL connection. Devices that are simply traversed by SSL traffic without terminating it are not affected.

This advisory will be updated as additional information becomes available. Cisco will release free software updates that address these vulnerabilities. Workarounds that mitigate these vulnerabilities may be available. This advisory is available at the following link:
