CVE-2013-4208  (opens in a new tab)
CWE-200  (opens in a new tab)

How to fix?

Upgrade Debian:unstable putty to version 0.63-1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream putty package and not the putty package as distributed by Debian. See How to fix? for Debian:unstable relevant fixed versions and status.

The rsa_verify function in PuTTY before 0.63 (1) does not clear sensitive process memory after use and (2) does not free certain structures containing sensitive process memory, which might allow local users to discover private RSA and DSA keys.
