Package        : libssh
Version        : 0.7.3-2+deb9u3
CVE ID         : CVE-2020-16135

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.

For Debian 9 stretch, this problem has been fixed in version
0.7.3-2+deb9u3.

We recommend that you upgrade your libssh packages.
