7.5 · HIGHOverview
CVE-2016-1000338 is a high-severity vulnerability affecting bouncycastle legion-of-the-bouncy-castle-java-crytography-api. It was published on June 1, 2018 and has a CVSS 3.1 base score of 7.5 (HIGH).
This vulnerability has a CVSS 3.1 base score of 7.5, rated HIGH. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.
Technical 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.
Remediation
Check the references section for vendor advisories and patches from bouncycastle. Update legion-of-the-bouncy-castle-java-crytography-api to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
