Bugs:	#699842
ID:	202007-29

Synopsis

Multiple vulnerabilities have been found in rssh, the worst of which could result in the arbitrary execution of code.

Background

rssh is a restricted shell, allowing only a few commands like scp or sftp. It is often used as a complement to OpenSSH to provide limited access to users.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
app-shells/rssh	<= 2.3.4_p3		All supported architectures

Description

Multiple vulnerabilities have been discovered in rssh. Please review the CVE identifiers referenced below for details.

Impact

Please review the referenced CVE identifiers for details.

Workaround

There is no known workaround at this time.

Resolution

Gentoo has discontinued support for rssh. We recommend that users unmerge rssh:

      # emerge --unmerge "app-shells/rssh"

NOTE: The Gentoo developer(s) maintaining rssh have discontinued support at this time. It may be possible that a new Gentoo developer will update rssh at a later date. OpenSSH (net-misc/openssh) may be able to provide similar functionality using its extensive configuration.
