GLSA-200412-01 : rssh, scponly: Unrestricted command execution

Synopsis :

The remote Gentoo host is missing one or more security-related

Description :

The remote host is affected by the vulnerability described in GLSA-200412-01
(rssh, scponly: Unrestricted command execution)

Jason Wies discovered that when receiving an authorized command from an
authorized user, rssh and scponly do not filter command-line options
that can be used to execute any command on the target host.

Impact :

Using a malicious command, it is possible for a remote authenticated
user to execute any command (or upload and execute any file) on the
target machine with user rights, effectively bypassing any restriction
of scponly or rssh.

Workaround :

There is no known workaround at this time.

Solution :

All scponly users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose '>=net-misc/scponly-4.0'
All rssh users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose '>=app-shells/rssh/rssh-2.2.3'
