USN-1591-1: xdiagnose update
2 October 2012
xdiagnose update
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 12.04 LTS
Summary
3rd party applications using xdiagnose could potentially be made to overwrite files.
Software Description
- xdiagnose - X.org diagnosis tool
Details
Alec Warner discovered that xdiagnose improperly handled temporary files in welcome.py when creating user-initiated archive files. While failsafeX does not use the vulnerable code, this update removes this functionality to protect any 3rd party applications which import the vulnerable code. In the default Ubuntu installation, this should be prevented by the Yama link restrictions.
Update instructions
The problem can be corrected by updating your system to the following package versions:
- Ubuntu 12.04 LTS
- xdiagnose - 2.5.2ubuntu0.1
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.
