CVSS v3.1
7.5
High
| Vector | AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N |
Name of the Vulnerable Software and Affected Versions
OpenSSL versions 1.0.1 through 1.0.1f
Description
The TLS and DTLS implementations in OpenSSL do not properly handle Heartbeat Extension packets, allowing remote attackers to obtain sensitive information from process memory via crafted packets that trigger a buffer over-read. This can be demonstrated by reading private keys. The issue is related to the handling of Heartbeat Extension packets.
Recommendations
For OpenSSL versions 1.0.1 through 1.0.1f, update to version 1.0.1g or later to resolve the issue. As a temporary workaround, consider disabling the Heartbeat Extension feature until a patch is available. Restrict access to sensitive information and private keys to minimize the risk of exploitation.
