Detail

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 11.10 - Ubuntu 11.04 - Ubuntu 10.10 - Ubuntu 10.04 LTS - Ubuntu 8.04 LTS

Summary:

Update Manager could be made to overwrite files as the administrator.

Software Description: - update-manager: GNOME application that manages apt updates - update-notifier: Daemon which notifies about package updates

Details:

David Black discovered that Update Manager incorrectly extracted the downloaded upgrade tarball before verifying its GPG signature. If a remote attacker were able to perform a man-in-the-middle attack, this flaw could potentially be used to replace arbitrary files. (CVE-2011-3152)

David Black discovered that Update Manager created a temporary directory in an insecure fashion. A local attacker could possibly use this flaw to read the XAUTHORITY file of the user performing the upgrade. (CVE-2011-3154)

This update also adds a hotfix to Update Notifier to handle cases where the upgrade is being performed from CD media.

Update instructions:

The problem can be corrected by updating your system to the following package versions:

Ubuntu 11.10:
update-manager 1:0.152.25.5

Ubuntu 11.04:
update-manager 1:0.150.5.1
update-notifier 0.111ubuntu2.1

Ubuntu 10.10:
update-manager 1:0.142.23.1
update-notifier 0.105ubuntu1.1

Ubuntu 10.04 LTS:
auto-upgrade-tester 1:0.134.11.1
update-notifier 0.99.3ubuntu0.1

Ubuntu 8.04 LTS:
update-manager 1:0.87.31.1

In general, a standard system update will make all the necessary changes.
