Synopsis ========
Multiple vulnerabilities have been found in rssh, allowing local attackers to bypass access restrictions.
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.

Description ===========
Multiple command line parsing and validation vulnerabilities have been discovered in rssh. Please review the CVE identifiers referenced below for details.
Impact ======
Multiple parsing and validation vulnerabilities can cause the restrictions set up by rssh to be bypassed.
Workaround ==========

Resolution ==========
All rssh users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=app-shells/rssh-2.3.4"
