Ubuntu Security Notice USN-1443-1
17th May, 2012
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 12.04 LTS
- Ubuntu 11.10
- Ubuntu 11.04
Update Manager could expose sensitive information in certain circumstances.
- update-manager - GNOME application that manages apt updates
It was discovered that Update Manager created system state archive files
with incorrect permissions when upgrading releases. A local user could
possibly use this to read repository credentials. (CVE-2012-0948)
Felix Geyer discovered that the Update Manager Apport hook incorrectly
uploaded certain system state archive files to Launchpad when reporting
bugs. This could possibly result in repository credentials being included
in public bug reports. (CVE-2012-0949)
The problem can be corrected by updating your system to the following package version:
- Ubuntu 12.04 LTS:
- update-manager-core 1:0.156.14.4
- Ubuntu 11.10:
- update-manager-core 1:0.152.25.11
- Ubuntu 11.04:
- update-manager-core 1:0.150.5.3
To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.
In general, a standard system update will make all the necessary changes.
