DISPUTED scp in OpenSSH through 8.3p1 allows command injection in the
scp.c toremote function, as demonstrated by backtick characters in the
destination argument. NOTE: the vendor reportedly has stated that they
intentionally omit validation of “anomalous argument transfers” because
that could “stand a great chance of breaking existing workflows.”

Notes
| Author | Note |
|---|---|
| seth-arnold | openssh-ssh1 is provided for compatibility with old devices that cannot be upgraded to modern protocols. Thus we may not provide security support for this package if doing so would prevent access to equipment. |
| mdeslaur | the upstream OpenSSH project will not be fixing this issue as it may result in breaking existing workflows. As such, we will not be fixing this issue in Ubuntu. |
