CVE ID         : CVE-2019-9894 CVE-2019-9895 CVE-2019-9897 CVE-2019-9898

Multiple vulnerabilities were found in the PuTTY SSH client, which could
result in denial of service and potentially the execution of arbitrary
code. In addition, in some situations random numbers could potentially be
re-used.

For the stable distribution (stretch), these problems have been fixed in
version 0.67-3+deb9u1.

We recommend that you upgrade your putty packages.
