Package : libreoffice
CVE ID : CVE-2018-16858

Alex Infuehr discovered a directory traversal vulnerability which could
result in the execution of Python script code when opening a malformed
document.

For the stable distribution (stretch), this problem has been fixed in
version 1:5.2.7-1+deb9u5. In addition this update fixes a bug in the
validation of signed PDFs; it would display an incomplete status message
when dealing with a partial signature.

We recommend that you upgrade your libreoffice packages.

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.
