"This update for putty fixes the following issues :

Update to new upstream release 0.72 [boo#1144547, boo#1144548]

  - Fixed two separate vulnerabilities affecting the
    obsolete SSH-1 protocol, both available before host key
    checking.

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

  - Fixed a crash in GSSAPI / Kerberos key exchange
    triggered if the server provided an ordinary SSH host
    key as part of the exchange."
