CVE-2016-1000342 (opens in a new tab)How to fix?
There is no fixed version for RHEL:10 bouncycastle.
NVD Description
Note: Versions mentioned in the description apply only to the upstream bouncycastle package and not the bouncycastle package as distributed by RHEL.
See How to fix? for RHEL:10 relevant fixed versions and status.
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.
