    Summary: Updated putty/filezilla/wxgtk packages fix security vulnerability

    Details: 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.
