Advisory:
========================

Updated libssh packages fix security vulnerability:

The code in src/sftpserver.c did not verify the validity of certain pointers
and expected them to be valid. A NULL pointer dereference could have been
occurred that typically causes a crash and thus a denial-of-service
(CVE-2020-16135).
