CVE-2020-15778

Published: 24 July 2020

** 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

AuthorNote

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.

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.
