![]() What is leaked secondary key material and how to recover? All this has to be done by the owners of the services. Even doing all this will still leave any traffic intercepted by the attacker in the past still vulnerable to decryption. Recovery from this leak requires patching the vulnerability, revocation of the compromised keys and reissuing and redistributing new keys. Any protection given by the encryption and the signatures in the X.509 certificates can be bypassed. Leaked secret keys allow the attacker to decrypt any past and future traffic to the protected services and to impersonate the service at will. These are the crown jewels, the encryption keys themselves. What is leaked primary key material and how to recover? In order to coordinate recovery from this bug we have classified the compromised secrets to four categories: 1) primary key material, 2) secondary key material and 3) protected content and 4) collateral. What is being leaked?Įncryption is used to protect secrets that may harm your privacy or security if they leak. programming mistake in popular OpenSSL library that provides cryptographic services such as SSL/TLS to the applications and services. Is this a design flaw in SSL/TLS protocol specification? Considering the long exposure, ease of exploitation and attacks leaving no trace this exposure should be taken seriously. However this bug has left large amount of private keys and other secrets exposed to the Internet. What makes the Heartbleed Bug unique?īugs in single software or library come and go and are fixed by new versions. When it is exploited it leads to the leak of memory contents from the server to the client and from the client to the server. Why it is called the Heartbleed Bug?īug is in the OpenSSL's implementation of the TLS/DTLS ( transport layer security protocols) heartbeat extension (RFC6520). Due to co-incident discovery a duplicate CVE, CVE-2014-0346, which was assigned to us, should not be used, since others independently went public with the CVE-2014-0160 identifier. CVE (Common Vulnerabilities and Exposures) is the Standard for Information Security Vulnerability Names maintained by MITRE. CVE-2014-0160 is the official reference to this bug.
