GHSA-qcj7-g2j5-g7r3 · 深刻度: high · エコシステム: maven — In Bouncy Castle JCE Provider ECDSA does not fully validate ASN.1 encoding of signature on verification
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.
