In yast2-printer up to and including version 4.0.2 the SMB printer settings don’t escape characters in passwords properly. If a password with backticks or simliar characters is supplied this allows for executing code as root. This requires tricking root to enter such a password in yast.

CNA Affected

  {
    "product": "yast2-printer",
