Two separate vulnerabilities affecting the obsolete SSH-1 protocol, both

Vulnerability in all the SSH client tools (PuTTY, Plink, PSFTP, and PSCP)
if a malicious program can impersonate Pageant.

Crash in GSSAPI / Kerberos key exchange triggered if the server provided
an ordinary SSH host key as part of the exchange.

Insufficient handling of terminal escape sequences, that should delimit
the pasted data in bracketed paste mode (CVE-2019-17068).

Possible information leak caused by SSH-1 disconnection messages
(CVE-2019-17069).

The putty package has been updated to version 0.73, fixing these issues
and other bugs.");
