{"schemaVersion":3,"id":"CVE-2007-6755","aliases":["DEBIAN-CVE-2007-6755"],"status":"published","duplicateOf":null,"title":null,"description":"The NIST SP 800-90A default statement of 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, which might allow context-dependent attackers to defeat cryptographic protection mechanisms by leveraging knowledge of those values.  NOTE: this is a preliminary CVE for Dual_EC_DRBG; future research may provide additional details about point Q and associated attacks, and could potentially lead to a RECAST or REJECT of this
