"It was discovered that the fix for the security vulnerability released
for rssh in 2.3.4-4+deb8u2 via DLA-1660-1 introduced a regression that
blocked scp(1) of multiple files from a server using rssh.

Please see <https://bugs.debian.org/921655> for more information.

For Debian 8 'Jessie', this issue has been addressed in rssh version
2.3.4-4+deb8u3.

We recommend that you upgrade your rssh packages.

NOTE: Tenable Network Security has extracted the preceding description
block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues."
