CVE-2011-0766
7.8 · HIGHOverview
CVE-2011-0766 is a high-severity vulnerability affecting erlang crypto. It was published on May 31, 2011 and has a CVSS 2.0 base score of 7.8 (HIGH).
This vulnerability has a CVSS 2.0 base score of 7.8, rated HIGH. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.
Technical Description
The random number generator in the Crypto application before 2.0.2.2, and SSH before 2.0.5, as used in the Erlang/OTP ssh library before R14B03, uses predictable seeds based on the current time, which makes it easier for remote attackers to guess DSA host and SSH session keys.
Remediation
Check the references section for vendor advisories and patches from erlang. Update crypto to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
