========================================================================== Ubuntu Security Notice USN-3946-1 April 11, 2019
rssh vulnerabilities ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 18.10 - Ubuntu 18.04 LTS - Ubuntu 16.04 LTS - Ubuntu 14.04 LTS
Summary:
rssh could be made to run arbitrary commands if it received specially crafted input.
Software Description: - rssh: Restricted shell allowing scp, sftp, cvs, svn, rsync or rdist
Details:
It was discovered that rssh incorrectly handled certain command-line arguments and environment variables. An authenticated user could bypass rssh's command restrictions, allowing an attacker to run arbitrary commands.
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 18.10: rssh 2.3.4-8ubuntu0.2
Ubuntu 18.04 LTS: rssh 2.3.4-7ubuntu0.1
Ubuntu 16.04 LTS: rssh 2.3.4-4+deb8u2ubuntu0.16.04.2
Ubuntu 14.04 LTS: rssh 2.3.4-4+deb8u2ubuntu0.14.04.2
In general, a standard system update will make all the necessary changes.
