Ubuntu: New Update Manager packages fix security vulnerabilities

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. 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.

Updated packages are available from security.ubuntu.com.
