CVE-2016-1000338
HIGH7.5EPSS 0.38%bouncycastle - security update
Published: 10/17/2018Modified: 4/28/2026
Description
In Bouncy Castle JCE Provider version 1.55 and earlier the DSA 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.
