This may allow one to perform Invalid Curve Attacks. Fix: https://github.com/opencryptoki/opencryptoki/commit/4e3b43c3d8844402c04a66b55c6c940f965109f0 (SOFT: Check the EC Key on C_CreateObject and C_DeriveKey) This commit should apply smooth on top of OCK 3.16.0, but also on OCK 3.15.0 or 3.15.1. EC support has been introduced in the Soft token with OCK 3.15.0. So all OCK versions >= 3.15.0 are affected. Earlier OCK releases are not affected. This problem need only to be fixed with 21.04 wherer 3.15.1 is included. + + [Test Plan] + + ?? + + + [Where problems could occur] + + Even assuming the underlying code is perfectly correct, the update + increases the API surface of the library slightly, which could provoke + namespace clashes where none existed before. + + If the EC checking code isn't correct, the soft token implementation + might reject some valid keys that would have previously gone through.
