GLSA-200502-28 : PuTTY: Remote code execution

High Nessus Plugin ID 17164

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.

Solution

All PuTTY users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=net-misc/putty-0.57'
