Description

`cryptoki` treated the CKA_ALLOWED_MECHANISMS ulValueLen byte count as a CK_MECHANISM_TYPE element count. A valid nonempty attribute returned through the safe `Session::get_attributes` API could cause construction of an out-of-bounds slice and undefined behavior. Possible consequences include a process crash or denial of service and potential disclosure of adjacent heap words. Upgrade to the fixed patch release for the cryptoki 0.10, 0.11, or 0.12 line.
