Debian Security Advisory DSA-4382-1 [email protected]
https://www.debian.org/security/ Moritz Muehlenhoff
February 02, 2019 https://www.debian.org/security/faq
Package : rssh
CVE ID : CVE-2019-3463 CVE-2019-3464
Nick Cleaton discovered two vulnerabilities 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 rsync support
could result in the bypass of this restriction, allowing the execution
of arbitrary shell commands.
For the stable distribution (stretch), these problems have been fixed in
version 2.3.4-5+deb9u2.
We recommend that you upgrade your rssh packages.
For the detailed security status of rssh please refer to
its security tracker page at:
https://security-tracker.debian.org/tracker/rssh
