Vulnerability Assessment Details

USN255-1 : openssh vulnerability

Vulnerability Assessment Summary
openssh vulnerability

Detailed Explanation for this Vulnerability Assessment

Summary :

These remote packages are missing security patches :
- openssh-client
- openssh-server
- ssh
- ssh-askpass-gnome


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 '*'), a possible hacker 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 :

Upgrade to :
- openssh-client-4.1p1-7ubuntu4.1 (Ubuntu 5.10)
- openssh-server-4.1p1-7ubuntu4.1 (Ubuntu 5.10)
- ssh-4.1p1-7ubuntu4.1 (Ubuntu 5.10)
- ssh-askpass-gnome-4.1p1-7ubuntu4.1 (Ubuntu 5.10)
