Summary
The ESnet security team discovered a vulnerability in rssh, a restricted shell that allows users to perform only scp, sftp, cvs, svnserve (Subversion), rdist and/or rsync operations. Missing validation in the scp support could result in the bypass of this restriction, allowing the execution of arbitrary shell commands. Please note that with the update applied, the '-3' option of scp can no longer be used.
