BIG-IP products are not affected because ECDSA and other elliptic curve algorithms are not enabled in the BIG-IP OpenSSL implementation. For information about elliptic curve cryptography support, refer to K12982: BIG-IP support for elliptic curve cryptography.
Vulnerability description and product information
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 using a timing attack and a lattice calculation.
