There is 1 open security issue in buster.
1 issue left for the package maintainer to handle:
Multiple path traversal vulnerabilities exist in smbserver.py in Impacket through 0.9.22. An attacker that connects to a running smbserver instance can list and write to arbitrary files via ../ directory traversal. This could potentially be abused to achieve arbitrary code execution by replacing /etc/shadow or an SSH authorized key.
You can find information about how to handle this issue in the security team's documentation.
