Fedora 30: FEDORA-2019-d1487c13ac Critical: rssh Code Execution Risk

fedora
Calendar Grey November 9, 2019
Dist Fedora Esm H88
Bolster the security of Fedora 30 by implementing crucial updates that tackle rssh vulnerabilities and their corresponding resolutions.
Fix CVE-2019-3463, CVE-2019-3464 and CVE-2019-1000018.

Summary

rssh is a restricted shell for use with OpenSSH, allowing only scp

and/or sftp. For example, if you have a server which you only want

to allow users to copy files off of via scp, without providing shell

access, you can use rssh to do that. It is a alternative to scponly.
