Description
This pull request fixes an incorrect error handling path in
ecc_sign_hash_internal.cmentioned in #801.When the input buffer exceeds
MAXBLOCKSIZE, the code previously jumped to the error label, potentially causingecc_freeto operate on an uninitializedpubkey.The error path has been corrected to jump to
errnokeyinstead, avoiding cleanup of an uninitialized key.Closes #801
