FreeBSD : putty -- buffer overflow vulnerability in ssh2 support (19518d22-2d05-11d9-8943-0050fc56d258)

High Nessus Plugin ID 37021


The remote FreeBSD host is missing a security-related update.


There is a bug in SSH2 support that allows a server to execute malicious code on a connecting PuTTY client. This attack can be performed before host key verification happens, so a different machine
-- man in the middle attack -- could fake the machine you are connecting to.


Update the affected package.
