There are 2 open security issues in buster.
2 issues left for the package maintainer to handle:
In goxmldsig (XML Digital Signatures implemented in pure Go) before version 1.1.0, with a carefully crafted XML file, an attacker can completely bypass signature validation and pass off an altered file as a signed one. A patch is available, all users of goxmldsig should upgrade to at least revision f6188febf0c29d7ffe26a0436212b19cb9615e64 or version 1.1.0
This affects all versions of package github.com/russellhaering/goxmldsig. There is a crash on nil-pointer dereference caused by sending malformed XML signatures.
You can find information about how to handle these issues in the security team's documentation.
