Vulnerability Assessment Details
PuTTY: Pre-authentication arbitrary code execution
Detailed Explanation for this Vulnerability Assessment
The remote host is affected by the vulnerability described in GLSA-200408-04
(PuTTY: Pre-authentication arbitrary code execution)
PuTTY contains a vulnerability permiting a malicious server to execute
arbitrary code on the connecting client before host key verification.
When connecting to a server using the SSH2 protocol a possible hacker 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.
There is no known workaround at this time. All users are encouraged to
upgrade to the latest available version of PuTTY.
All PuTTY users should upgrade to the latest version:
# emerge sync
# emerge -pv ">=net-misc/putty-0.55"
# emerge ">=net-misc/putty-0.55"
