A remotely triggerable memory overwrite in RSA key exchange in PuTTY before
0.71 can occur before host key verification (CVE-2019-9894).

In PuTTY versions before 0.71 on Unix, a remotely triggerable buffer
overflow exists in any kind of server-to-client forwarding (CVE-2019-9895).

Multiple denial-of-service attacks that can be triggered by writing to the
terminal exist in PuTTY versions before 0.71 (CVE-2019-9897).

Potential recycling of random numbers used in cryptography exists within
PuTTY before 0.71 (CVE-2019-9898).

The putty package has been updated to version 0.71 and the filezilla package
has been updated and patched to fix these issues.

wxgtk has been updated to fix an assert when starting filezilla.
