Description Pedro Sampaio 2018-06-07 14:27:08 EDT 
In the Bouncy Castle JCE Provider version 1.55 and earlier ECDSA does not fully
validate ASN.1 encoding of signature on verification. It is possible to inject
extra elements in the sequence making up the signature and still have it
validate, which in some cases may allow the introduction of 'invisible' data
into a signed structure.

Fedora already carries bouncycastle newer than 1.56, so I will close this bug.
