===========================================================
Ubuntu Security Notice USN-255-1	  February 21, 2006
openssh vulnerability
CVE-2006-0225
===========================================================

A security issue affects the following Ubuntu releases:

Ubuntu 4.10 (Warty Warthog)
Ubuntu 5.04 (Hoary Hedgehog)
Ubuntu 5.10 (Breezy Badger)

The following packages are affected:

openssh-client

The problem can be corrected by upgrading the affected package to
version 1:3.8.1p1-11ubuntu3.3 (for Ubuntu 4.10), 1:3.9p1-1ubuntu2.2
(for Ubuntu 5.04), or 1:4.1p1-7ubuntu4.1 (for Ubuntu 5.10).  In
general, a standard system upgrade is sufficient to effect the
necessary changes.

Details follow:

Tomas Mraz discovered a shell code injection flaw in scp. When doing
local-to-local or remote-to-remote copying, scp expanded shell escape
characters. By tricking an user into using scp on a specially crafted
file name (which could also be caught by using an innocuous wild card
like '*'), an attacker could exploit this to execute arbitrary shell
commands with the privilege of that user.

Please be aware that scp is not designed to operate securely on
untrusted file names, since it needs to stay compatible with rcp.
Please use sftp for automated systems and potentially untrusted file
names.
