OpenSSL Heartbeat Extension Vulnerability in Multiple Cisco Products
Advisory ID: cisco-sa-20140409-heartbleed
Revision 1.0
For Public Release 2014 April 9 03:00 UTC (GMT)
Summary
=======
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.
Cisco is currently investigating its product line to determine which products may be affected by this vulnerability and the impact on the affected product. 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.
