Synopsis :

The remote Gentoo host is missing one or more security-related
patches.

Description :

The remote host is affected by the vulnerability described in GLSA-200502-28
(PuTTY: Remote code execution)

Two vulnerabilities have been discovered in the PSCP and PSFTP
clients, which can be triggered by the SFTP server itself. These issues
are caused by the improper handling of the FXP_READDIR response, along
with other string fields.

Impact :

An attacker can setup a malicious SFTP server that would send
these malformed responses to a client, potentially allowing the
execution of arbitrary code on their system.

Workaround :

There is no known workaround at this time.
