CVE-2011-1945
2.6 · LOWOverview
CVE-2011-1945 is a low-severity vulnerability affecting openssl openssl. It was published on May 31, 2011 and has a CVSS 2.0 base score of 2.6 (LOW).
This vulnerability has a CVSS 2.0 base score of 2.6, rated LOW. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.
Technical Description
The elliptic curve cryptography (ECC) subsystem in OpenSSL 1.0.0d and earlier, when the Elliptic Curve Digital Signature Algorithm (ECDSA) is used for the ECDHE_ECDSA cipher suite, does not properly implement curves over binary fields, which makes it easier for context-dependent attackers to determine private keys via a timing attack and a lattice calculation.
Remediation
Check the references section for vendor advisories and patches from openssl. Update openssl 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.
