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.
CVE (Common Vulnerabilities and Exposures) is the Standard for Information Security Vulnerability Names maintained by MITRE.
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.
These may contain technical details such as memory addresses and security measures such as canaries used to protect against overflow attacks.
These have only contemporary value and will lose their value to the attacker when Open SSL has been upgraded to a fixed version.
