Description:
Daniel Kahn Gillmor has discovered a weakness in PuTTY, which can be exploited by malicious, local users to gain knowledge of sensitive information.

The weakness is caused due to "puttygen" generating new private keys with potentially insecure default file permissions, which can be exploited to disclose a user's private key.

The weakness is confirmed in version 0.58 on a Linux system. Other versions may also be affected.
