Ubuntu sudo vulnerablity


Recommended Posts

I know a few of you run Ubuntu linux figured i share this.

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:


The problem can be corrected by upgrading the affected package to

version 1.6.7p5-1ubuntu4.4 (for Ubuntu 4.10), 1.6.8p5-1ubuntu2.3 (for

Ubuntu 5.04), or 1.6.8p9-2ubuntu2.2 (for Ubuntu 5.10). In general, a

standard system upgrade is sufficient to effect the necessary changes.

Details follow:

Charles Morris discovered a privilege escalation vulnerability in

sudo. On executing Perl scripts with sudo, various environment

variables that affect Perl's library search path were not cleaned

properly. If sudo is set up to grant limited sudo execution of Perl

scripts to normal users, this could be exploited to run arbitrary

commands as the target user.

This security update also filters out environment variables that can

be exploited similarly with Python, Ruby, and zsh scripts.

Please note that this does not affect the default Ubuntu installation,

or any setup that just grants full root privileges to certain users.
