Gentoo Linux Security Advisory

Title: PuTTY: Pre-authentication arbitrary code execution (GLSA 200408-04)
Severity: normal
Exploitable: remote
Date: August 05, 2004
Updated: May 22, 2006
Bug(s): #59383
ID: 200408-04

Synopsis


PuTTY contains a vulnerability allowing a SSH server to execute arbitrary
code on the connecting client.


Background


PuTTY is a free implementation of Telnet and SSH for Win32 and Unix
platforms, along with an xterm terminal emulator.


Affected Packages

Package: net-misc/putty
Vulnerable: <= 0.54
Unaffected: >= 0.55
Architectures: All supported architectures


Description


PuTTY contains a vulnerability allowing a malicious server to execute
arbitrary code on the connecting client before host key verification.


Impact


When connecting to a server using the SSH2 protocol an attacker is able
to execute arbitrary code with the permissions of the user running
PuTTY by sending specially crafted packets to the client during the
authentication process but before host key verification.


Workaround


There is no known workaround at this time. All users are encouraged to
upgrade to the latest available version of PuTTY.


Resolution


All PuTTY users should upgrade to the latest version:
Code:
# emerge sync
   
    # emerge -pv ">=net-misc/putty-0.55"
# emerge ">=net-misc/putty-0.55"
