Ubuntu 4.10 / 5.04 / 5.10 : openssh vulnerability (USN-255-1)

Ubuntu Security Notice (C) 2006-2013 Canonical, Inc. / NASL script (C) 2006-2013 Tenable Network Security, Inc.


Synopsis :

The remote Ubuntu host is missing one or more security-related patches.

Description :

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.

Solution :

Update the affected packages.

Risk factor :

Medium / CVSS Base Score : 4.6
