Vulnerability details
The vulnerability allows a remote attacker to decrypt sensitive information.
The vulnerability exists due to the Dual Elliptic Curve Deterministic Random Bit Generation (Dual_EC_DRBG) algorithm contains point Q constants with a possible relationship to certain "skeleton key" values. A remote context-dependent attacker can defeat cryptographic protection mechanisms by leveraging knowledge of those values.
