Package : rssh
Version : 2.3.4-4+deb8u1
CVE ID : CVE-2019-1000018
Debian Bug : 919623
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.
For Debian 8 "Jessie", this problem has been fixed in version
2.3.4-4+deb8u1.
We recommend that you upgrade your rssh packages.
