Implications include an assertion failure, which could > be used for denial-of-service, when verifying signatures on the > secp_224r1 and secp521_r1 curves. More details in NEWS file below. > > Upgrading is strongly recomended. Are there plans to make a new 3.5 release including these fixes? Alternatively, could you provide guidance as to which commits should be cherry-picked in 3.5 for downstream distros? I=E2=80=99m asking because in Guix, the easiest way for us to deploy the fi= xes on the =E2=80=98master=E2=80=99 branch would be by =E2=80=9Cgrafting=E2=80= =9D a new Nettle variant ABI-compatible with 3.5.1, which is the one packages currently depend on. Thanks in advance, Ludo=E2=80=99.
